ELEGOO 120pcs Multicolored Dupont Wire
120-piece mixed-connector set
20-centimeter ribbon length
2.54 mm header compatibility
Copper-clad aluminum conductors
The ELEGOO 120-piece Dupont wire set combines male-to-male, male-to-female, and female-to-female leads in one organized collection. With a 4.8 rating, it stands out as a versatile and well-received option for breadboard construction, sensor testing, display connections, and general controller-module wiring. Its most useful feature is the balanced selection of connector types rather than a large number of nearly identical leads.
Pros
- Includes three connector styles
- Strong 4.8 customer rating
- Separable multicolored ribbons
- Useful across many prototype tasks
- Compact 20-centimeter footprint
Cons
- Fixed ribbon cable length
- Not intended for high-current wiring

Each configuration includes 40 wires, and every lead measures 20 centimeters. That length is practical for links between nearby breadboard rows or between a prototyping board and an adjacent module. The conductors are presented as multicolored, separable ribbons, allowing users to remove only the number of wires needed for a circuit. Color coding also makes power, ground, data, and control paths easier to follow when a temporary prototype becomes complex.
The kit uses 2.54 millimeter connections, matching common breadboards and 0.1-inch female sockets and male headers. It is important to note that the conductor is described as copper-clad aluminum with PVC insulation, not pure copper. It is also intended for temporary, low-voltage signal prototyping rather than mains electricity, automotive jumpers, or other high-current applications. Those limits are reasonable for a lightweight Dupont assortment and should be respected for safety.
This is a strong choice for beginners who want one ribbon capable of linking different header types, as well as experienced users who frequently mix breadboard, sensor, and display connections. It may not suit a project requiring many different span lengths because every lead is 20 centimeters long. Even so, the combination of three connector formats, useful color coding, and a strong rating makes this an excellent general-purpose starting kit.
Three Connector Types Simplify Mixed Projects
Male-to-male, male-to-female, and female-to-female leads cover most standard prototyping links. This versatility reduces the need to buy several separate ribbon styles when a circuit uses more than one header arrangement.
Color Coding Improves Circuit Troubleshooting
Distinct insulation colors help identify power, ground, signals, and controls at a glance. Because the ribbon is separable, builders can retain a grouped color convention while removing only the wires a particular circuit requires.

Includes plastic storage box
The AUSTOR 560-piece kit is a broad breadboard assortment built around preformed, right-angled male-to-male leads. It carries a 4.5 rating and includes 14 lengths ranging from very short local links to 125-millimeter runs. That range is the main attraction: a single board can use several small connections and a few longer links without requiring separate purchases.
Pros
- Broad range of fourteen lengths
- Pre-stripped and preformed ends
- Includes organized storage case
- Suitable for repeated prototyping
- Flexible enough to reshape
Cons
- Male-to-male connectors only
- Some wires may feel soft
We may earn a commission when you buy through this link, at no additional cost to you.
All wires use 24 AWG construction and are supplied pre-stripped and preformed, so they can be inserted directly into compatible breadboard sockets. The product description notes that the leads are somewhat soft, which can be helpful when changing a layout or adapting a connection during testing. A tweezer is not included with this particular kit, so careful placement is especially useful when working with closely spaced rows.
The free plastic box is a meaningful practical benefit for a kit containing hundreds of small pieces. Separate lengths can be kept from becoming an untangled mass on a workbench, which saves time during repeated classroom, hobby, or electronics experiments. The trade-off is that the set supports only male-to-male connections and uses fixed, right-angle geometry rather than the longer reach of flexible Dupont cables.
Choose this kit when your work is primarily standard breadboard prototyping and you value a balanced range of short and long links. It is less suitable for connecting female headers to male pins without an additional adapter, and the soft wire may demand a light touch during insertion. Overall, the comprehensive assortment and practical organization make it a strong everyday choice.
Fourteen Lengths Cover Real Circuit Layouts
The selection from 2 millimeters through 125 millimeters lets builders match short row-to-row links with longer connections between separate boards. This reduces excess wire clutter and makes it easier to create a clean prototype from the outset.
Preformed Ends Save Setup Time
Pre-stripped and preformed leads eliminate the preparation required by raw wire. The right-angle shape also keeps connections visually separate from the breadboard surface, which can be helpful when inspecting or rearranging a temporary circuit.

We may earn a commission when you buy through this link, at no additional cost to you.
The wires are solid 24 AWG, male-to-male, pre-cut, pre-stripped, and preformed. Lengths begin at 2 millimeters and continue through 5, 7, 10, 12, 15, 17, 20, 22, 25, 50, 75, 100, and 125 millimeters. This granularity makes the kit appropriate for classrooms, electronics labs, frequent prototyping, and projects involving multiple boards or widely separated header points.
A plastic storage box keeps the many sizes organized, while the tweezer reduces the need to grip wires directly. These included accessories improve usability, although they do not expand the connector types. The kit remains male-to-male, so it cannot directly replace female-to-female or mixed Dupont ribbon leads. Buyers with a large number of one-off female-header connections may need to supplement it.
This is our premium selection because of the combination of quantity, precise length coverage, and the included tool. The 840-piece format is more than a casual user might consume, but for a shared lab, classroom, maker space, or regular electronics hobbyist, it offers exceptional flexibility. For anyone building a dependable breadboard bench, it is one of the most complete options in this guide.
Unmatched Quantity Supports Busy Workbenches
With 840 preformed wires, the kit is designed for repeated builds rather than a single demonstration. The large count is especially valuable in classrooms and shared workspaces where wires are frequently removed, lost, or rearranged.
Bent Tweezer Improves Wire Handling
The included bent tweezer offers better control than fingertips when placing tiny preformed leads into breadboard holes. It is particularly useful with the softer wires commonly found in solderless prototyping kits.

PVC insulation with copper
Compartmentalized plastic box
This 840-piece breadboard jumper kit combines 14 wire lengths with colorful PVC insulation and a compartmentalized storage box. Unlike several neighboring products, its stated length range starts at 3 millimeters rather than 2 millimeters. It does not have a supplied customer rating, so the decision should rely on its stated construction, variety, and intended applications rather than a numerical review history.
Pros
- Extensive range of sizes
- Color-coded insulation aids tracing
- Right angles already formed
- Separate storage compartments
- Broad electronics application range
Cons
- No customer rating supplied
- Connector details are not specified
We may earn a commission when you buy through this link, at no additional cost to you.
Each of the 14 sizes is represented by 60 wires, giving 840 total pieces. The assortment includes short links for neighboring breadboard holes and long leads reaching 125 millimeters. Right angles are already formed for direct placement, while the multiple insulation colors help users separate and identify different circuit paths. The stated PVC-and-copper construction is intended to provide flexible, stable connections for temporary electronics projects.
A major advantage is the compartmentalized plastic case, which separates the wires by length and reduces searching or tangling. That organization is especially valuable with a collection this large. The listing also describes a wide range of uses, including electronic DIY, PCB projects, communication equipment, instruments, displays, toys, and industrial programming controls.
The listing does not explicitly identify the terminal gender or pitch, so buyers should check the product imagery and current listing details if their circuit requires a specific male or female connector. It is best for users who value color coding, right-angle convenience, and extensive length choice over a precisely stated mixed-connector configuration. Subject to that compatibility check, it remains a useful, well-organized breadboard assortment.
Color Makes Complex Circuits Easier to Read
Vibrant insulation lets builders assign consistent colors to power, ground, data, and control lines. This visual organization is useful even when a breadboard contains several unrelated test circuits.
Compartments Keep 840 Wires Manageable
Separating the collection by length makes it easier to select the correct lead and return it to the proper section. The case therefore serves as both storage and a visual inventory system.

We may earn a commission when you buy through this link, at no additional cost to you.
Each wire is supplied with stripped ends and preformed right-angled leads for direct insertion into a breadboard. This eliminates manual cutting, stripping, and bending, which is a meaningful time saver when recreating a circuit or laying out a long series of test connections. The package is kept in a plastic box so different lengths can be stored together without immediately becoming difficult to sort.
The stated applications are broad, covering prototyping, LED strips, test circuits, computers, electronic communications, instruments, meters, industrial controls, cameras, card readers, displays, toys, and PCB projects. Such versatility is partly a function of the large assortment: whatever span a circuit demands, there is likely a suitable length already in the case.
Its main limitation is connector format. Male-to-male leads are ideal for standard breadboard rows but do not directly connect a female socket to another female socket. The product also lists no tweezer or other handling accessory. Even so, the strong rating, useful length granularity, and ready-made construction make this a compelling general breadboard bundle.
Fine Length Granularity Reduces Circuit Clutter
Fourteen choices allow users to select a lead that closely matches the distance between components. Shorter choices are especially useful for compact circuits where long jumpers would obstruct neighboring connections.
Ready-Made Leads Accelerate Prototyping
Stripped and preformed ends mean each connection can be inserted without preparation. For repeat testing or classroom work, that saved setup time can be more valuable than adding another accessory to the kit.

This mixed jumper wire kit stands apart by combining standard preformed U-shape breadboard wires with 65 flexible, solderless cables. It holds a 4.4 rating and includes a tweezer and plastic storage case. Rather than maximizing one connector category, it aims to cover several circuit-building styles within a single organized package.
Pros
- Combines rigid and flexible leads
- Fourteen standard breadboard lengths
- Four flexible cable sizes
- Tool supports easier placement
- Durable storage box
Cons
- Less focused on one wire format
- Total wire count is less than 840
We may earn a commission when you buy through this link, at no additional cost to you.
The rigid section contains 24 AWG male-to-male wires in 14 lengths, from 2 through 125 millimeters. Their pre-stripped, right-angled ends suit direct breadboard insertion. The flexible section adds 65 reusable cables in four lengths: 11, 16, 21, and 26 centimeters. Because the flexible leads can connect through pin connections, they offer another way to reach between circuit points without soldering.
The added tweezer is useful because the product description specifically notes that breadboard wires can be somewhat soft. A proper tool gives users more control when inserting or removing leads around tight rows. The durable plastic case makes it easier to carry the assortment and keep the smallest pieces together in a classroom, workshop, or home electronics space.
This kit is ideal when a project needs both compact right-angle links and longer flexible runs. Its mixed format is less suitable for someone who wants the largest possible number of identical male-to-male wires or a clearly stated female-to-female assortment. Within its broader purpose, however, it offers flexible cable options and useful handling equipment alongside a comprehensive set of standard spans.
Flexible Cables Expand Routing Options
The four lengths of flexible cable provide practical links when a circuit must bend or move around a breadboard. They complement the rigid U-shape wires rather than duplicating the same short connection pattern.
Tweezer Helps With Soft Leads
Breadboard jumpers can be difficult to position by hand, especially in crowded holes. The included tweezer improves control and helps reduce accidental bending or displacement of nearby connections.

- Reusable insulated construction
- Pre-stripped right-angle leads
- Includes plastic storage box
Cons
- Male-to-male format limits compatibility
- Fewer total wires than 840-piece kits
We may earn a commission when you buy through this link, at no additional cost to you.
The size list starts at 2 millimeters and progresses through 5, 7, 10, 12, 15, 17, 20, 22, 25, 50, 75, 100, and 125 millimeters. This is a more useful distribution than a collection dominated by one or two lengths. Short wires handle nearby breadboard holes, while the larger sizes bridge separate boards or more distant header positions.
All leads are described as colored, pre-stripped, and preformed at right angles. The result is a fast, solderless workflow for prototypes, LED-strip tests, and other temporary circuits. A plastic storage box is included, helping contain hundreds of small pieces and separate the length groups for easier retrieval.
The format remains male-to-male, so the kit is not a complete solution for projects dominated by female headers. It also contains fewer total wires than the 840-piece options, but the equal 40-piece allocation makes it a balanced middle ground. Buyers who want broad length support, a strong rating, and straightforward right-angle breadboard wiring will find this option especially convenient.
Even Piece Distribution Balances Common Needs
Forty pieces at every length ensure that short and long sizes are equally available. This avoids a situation where a kit has plenty of one span but too few of another needed for a complete layout.
Reusable Leads Support Iterative Prototyping
Insulated, preformed wires are intended to be connected, removed, and reused as a design changes. That makes the kit practical for learning, experimentation, and temporary diagnostic circuits.

- Broad stated size range
- Eight-color wire selection
- Ready for immediate insertion
- Includes storage box
Cons
- Lowest rated product here
- Exact count per length is unspecified
We may earn a commission when you buy through this link, at no additional cost to you.
The listing states that the conductors are copper and the insulation is PVC, with white, red, yellow, green, blue, gray, and orange represented. Preformed, right-angled, pre-stripped ends are ready for direct breadboard insertion. The 140 pieces are packed in a plastic box, which is particularly useful for keeping a manageable collection together compared with larger eight-hundred-piece kits.
The stated compatibility includes DIY shields, Arduino-style boards, and Raspberry Pi projects, along with general breadboard work. Buyers should still confirm the physical header spacing and connector type in the current listing because the product description does not provide a detailed per-length piece count. A compact kit also means fewer spare pieces if many connections are damaged or temporarily misplaced.
Choose this product when you want several sizes without carrying a very large inventory. It works well for focused electronics builds and mixed-color circuits where basic right-angle breadboard links are sufficient. Those wanting hundreds of identical pieces, mixed Dupont genders, or the highest stated rating may prefer another option, but the DEVMO set remains a straightforward choice for everyday prototyping.
Compact Inventory Suits Focused Builds
A smaller assortment is easier to keep organized and may be more appropriate for a single project or home workbench. It also provides enough variety to accommodate different connection distances without overwhelming the user.
Multiple Colors Support Visual Circuit Mapping
The stated palette supports basic color-coded wiring practices. Separate colors can make power and signal paths easier to identify while a prototype is being inspected or rearranged.

Fourteen sizes from 3–125 mm
Copper-plated core construction
Separate compartment storage
The 840-piece pre-stripped and pre-formed kit is designed for breadboard and circuit-board prototyping with right-angle connections. It has a 4.0 rating, and its defining feature is a large inventory spread evenly across 14 lengths. Each size is represented by 60 pieces, providing enough wire for repeated builds without favoring only one connection distance.
Pros
- Large inventory for busy labs
- Fourteen precise length options
- Flexible insulation for reshaping
- Right-angle ends need no preparation
- Organized case simplifies selection
Cons
- Lowest rated numerical result
- Gender and pitch are not specified
We may earn a commission when you buy through this link, at no additional cost to you.
The listed lengths begin at 3 millimeters and continue through 5, 7, 10, 12, 15, 17, 20, 22, 25, 50, 75, 100, and 125 millimeters. The leads use a copper-plated core and flexible outer insulation. They can be reshaped for tight spaces, while the pre-stripped and preformed right-angle design eliminates the need for manual wire preparation.
A sturdy plastic case includes separate compartments for each length. This arrangement supports quick identification and reduces the chance of mixing wires or losing small pieces. The stated applications include electronic DIY, Arduino experiments, PCB testing, communications equipment, instruments, industrial controls, cameras, displays, and other electronic devices.
Because the listing does not explicitly state connector gender or pitch, compatibility should be confirmed before purchase. Its 4.0 rating also suggests considering the supplied customer feedback more closely than with the higher-rated kits. Even so, the combination of quantity, flexible construction, and strong organization makes this a practical option for a high-volume bench.
Reshaping Helps Fit Tight Layouts
The flexible insulation allows preformed leads to bend where a rigid connection would be awkward. This is useful when the standard right-angle geometry does not perfectly match a component position.
Separate Compartments Enable Fast Selection
A dedicated area for each length makes the kit faster to use than a loose bundle of wires. It also helps return unused leads to the correct section after a prototype is dismantled.

The 120-piece 20-centimeter Dupont kit is a focused mixed-gender set with 40 female-to-female, 40 male-to-female, and 40 male-to-male leads. Its 4.7 rating makes it one of the strongest-reviewed products here. Rather than offering many span lengths, it concentrates on three essential connector combinations at one consistent cable length.
Pros
- Strong 4.7 customer rating
- Even distribution across connector types
- Nickel-plated brass terminals
- Twelve-core pure copper cable
- Ten-color separable ribbon
Cons
- Only one cable length
- Not a full assortment of spans
We may earn a commission when you buy through this link, at no additional cost to you.
The leads use standard 2.54-millimeter pitch with nickel-plated brass terminals. The stated twelve-core pure copper construction and multicolored PVC ribbon offer a clear construction specification, while ten colors help separate connections. The ribbon format is separable, allowing users to remove individual wires or smaller groups and match a specific breadboard or module layout.
A 20-centimeter lead is long enough to bridge nearby breadboard rows or connect a controller to an adjacent sensor or display without excessive slack. It is not as adaptable to widely separated boards as a kit containing 100- and 125-millimeter wires. The fixed length does, however, make component inventory and cable management more predictable.
This kit is an excellent choice for projects using standard 0.1-inch headers and a mixture of male and female sockets. It is less suitable for circuits needing multiple span lengths or nonstandard spacing. With its balanced gender distribution, stated terminal construction, and strong rating, it is a versatile first kit or a useful addition to a workbench with a focused set of standard connections.
Three Genders Cover Common Header Links
Equal quantities of male-to-male, male-to-female, and female-to-female wires cover the most common breadboard and module arrangements. That balance makes the kit easier to use than a single-gender collection.
Standard Pitch Supports Broad Compatibility
The 2.54-millimeter connectors are widely used on solderless breadboards, prototyping boards, sensors, and controller modules. This standardized format gives the kit more flexibility than specialty-sized wiring.

Buying Guide – How to Choose the Best 90 Degree Jumper Wires
The right jumper wire kit depends on connector gender, board spacing, required span, circuit type, and how often the wires will be reorganized. These factors help distinguish a useful mixed Dupont set from a comprehensive collection of preformed breadboard leads.
Connector Type and Gender
Start by identifying every connection your circuit requires. Male-to-male wires suit standard breadboard holes and compatible male headers, male-to-female wires connect male pins to female sockets, and female-to-female wires bridge two female headers. A mixed set offers flexibility, while a dedicated male-to-male assortment is simpler and usually provides more preformed right-angle pieces for the same inventory size.
Header Pitch and Compatibility
Pitch is the distance between adjacent connector positions. Most standard breadboards and 0.1-inch module headers use 2.54-millimeter spacing, but specialized boards can differ. Match the stated pitch of the kit to the physical header before ordering, and check the connector gender as well. A wire that looks visually similar can still fail to connect if its housing, pin spacing, or terminal arrangement does not match.
Wire Length Assortment
Short leads suit neighboring breadboard rows, while longer options connect distant modules or separate boards. Kits with 14 lengths provide better flexibility than a single-length collection. Very short links reduce clutter, and longer links eliminate the need to improvise connections across substantial gaps. Consider both the minimum and maximum span, especially if you move between compact and multi-board experiments.
Piece Count and Distribution
A larger piece count is useful for classrooms, shared workspaces, and frequent prototype changes, but quantity alone does not guarantee usefulness. Check how many wires are allocated to each length. An 840-piece set with an even distribution can be more versatile than a similarly sized kit dominated by one span. Smaller collections may be adequate for a single focused project and are easier to manage.
Right-Angle and Ribbon Design
Preformed right-angle wires insert quickly and keep the connection profile compact, while separable ribbon cables can be split into smaller groups. Rigid right-angle leads are useful for fixed breadboard layouts. Flexible ribbon wires may be easier to route around modules, but their fixed overall length provides less freedom than a set of preformed leads in many sizes.
Conductor and Insulation
The listed materials indicate whether a kit is appropriate for ordinary low-voltage prototyping. Copper, copper-clad aluminum, and copper-plated cores appear across the selections, while PVC is the standard insulation mentioned for most. These wires are generally intended for temporary signal connections. They should not be treated as automotive jumper cables, high-current leads, or safe wiring for mains electricity.
Storage and Included Tools
Hundreds of small wires become difficult to manage without a compartmentalized case. Most large kits include a plastic box, and several also provide a bent tweezer for handling soft leads. Storage is not merely cosmetic: labeled or separated lengths speed up selection and reduce tangled bundles. A tweezer can also improve control when inserting wires into tightly spaced breadboard holes.
Prototyping Scope and Safety
Most of these products are designed for breadboards, prototyping boards, test circuits, displays, sensors, and similar educational or hobby projects. Confirm that the intended board accepts the connector format and that the wire gauge is appropriate for the current involved. Jumper wires are intended for temporary low-voltage signal work and should not replace purpose-built power wiring.
How to Use and Care for Your 90 Degree Jumper Wires
Plan the circuit before inserting wires, especially when using a kit with many lengths and colors. Sketch the intended paths, assign consistent colors for power, ground, data, and control signals, and choose the shortest lead that comfortably reaches each connection. This prevents excess wire from blocking nearby breadboard holes and makes the completed layout easier to inspect.
Connect the circuit in stages. Begin with power and ground links, confirm that the board is powered as intended, and then add sensor, display, or controller connections. Insert male-to-male or mixed Dupont leads straight into compatible sockets without forcing them. For soft preformed wires, use a tweezer when available, grip near the end, and avoid pulling from the flexible span.
After testing, switch off and disconnect power before rearranging the breadboard. Hold the connector housing rather than the wire when removing a lead, and store each length in its designated case compartment. Inspect occasionally for loose pins, damaged insulation, or a wire that no longer seats firmly, replacing questionable leads rather than forcing an unreliable connection.
Frequently Asked Questions
What are 90 degree jumper wires used for?
They create temporary, solderless connections between breadboard rows, prototyping boards, sensors, displays, and compatible controller headers. Their preformed right-angle ends make short connections quickly and keep the wiring profile relatively compact. They are most suitable for low-voltage electronics experiments rather than permanent installations.
Are right-angle jumper wires better than straight wires?
Right-angle wires can be neater on crowded breadboards because the connection body turns parallel to the board. Straight wires may be more convenient for reaching around components or creating temporary diagonal routes. The right choice depends on the layout, available space, and the connector orientation required by your project.
What does 2.54 mm pitch mean?
It means adjacent connector positions are separated by 2.54 millimeters, equivalent to 0.1 inch. This is the common spacing used by many breadboards and development-module headers. You should confirm both pitch and connector gender before inserting a wire into a board.
Should I choose fixed-length ribbons or mixed-length kits?
Fixed-length ribbons are convenient for consistent connections between nearby modules and can provide male-to-female or female-to-female options. Mixed-length male-to-male kits are better when breadboard spacing varies widely. Choose based on whether your modules sit close together or your circuit uses rows at many different distances.
Can jumper wires be reshaped?
Some soft preformed leads can be bent carefully to fit a layout, but repeated sharp bends may damage the conductor or strain the connection. A fitting length is more reliable than forcing a rigid wire into an unusual shape. Avoid aggressive reshaping, especially near the exposed terminal.
Are these jumper wires safe for mains voltage?
No. These products are intended for temporary, low-voltage signal prototyping on compatible electronic boards. They are not designed as mains-voltage wiring, high-current power leads, or automotive jumper cables. Use appropriately rated equipment and purpose-built wiring for those applications.
How should I keep hundreds of jumper wires organized?
Choose a kit with a divided plastic case, and keep each length in its own compartment. Sorting by size makes it easier to select the correct lead and helps prevent tangling. Returning wires to the case after each session also reduces the chance of losing small pieces or mixing incompatible connector types.
What does a pre-stripped and preformed jumper wire mean?
Pre-stripped means the conductor is already prepared for insertion into a breadboard or compatible socket. Preformed means the end is bent into a right angle. Together, these features reduce setup time and eliminate the need to cut, strip, and bend each lead before use.
Final Thoughts on Choosing the Best 90 Degree Jumper Wires
The ELEGOO mixed-connector set is the most practical all-around starting point, while the AUSTOR assortment is a strong choice for conventional breadboard work across many spans. The Makeronics kit earns the premium distinction through its 840-piece inventory, 14 lengths, storage box, and included tweezer. Each serves a different need while retaining the core benefit of quick, solderless connections.
Prioritize connector gender, pitch, and required lengths before considering quantity. Mixed Dupont sets are best for diverse modules, while male-to-male preformed kits excel on standard breadboards. For frequent work, a divided storage case and a handling tool can matter more than an extra few wires, especially when every connection must be placed accurately.
Product availability, ratings, and prices can change, so check the current listing and recent customer feedback before ordering. Confirm that the wire gauge, pitch, and connector style match your board and that the intended use remains within the product's low-voltage prototyping scope. With those checks completed, the right kit can make circuit work faster, cleaner, and more organized.
