Unlock New Capabilities

• Past Projects (Prerequisites): If you've already experimented with building basic circuits on a breadboard using long, flexible male-to-male jumper wires, you already understand how to route signals and power — which means you're ready to upgrade your prototyping skills from a chaotic "bird's nest" of wires to a clean, professional layout.
• Feature Upgrade (What This Unlocks): This 140-piece U-shape jumper wire kit unlocks the ability to build low-profile, highly organized breadboard circuits. By laying wires flat against the board, you can easily troubleshoot complex logic gate arrays, route clean power rails without obstructive loops, and prevent accidental wire disconnections when reaching in to swap out ICs or sensors.
• Effort Level & Minimum Hardware
• Effort Level: Beginner

Minimum hardware to get started:

• Solderless Breadboard (400 or 830 tie points): required as the base platform to insert these solid-core wires and build your circuits.
• Tweezers or Needle-Nose Pliers (Optional but recommended): highly useful for precisely gripping and inserting the shortest U-shape wires into tight breadboard spaces without bending the exposed pins.

Included in the Box:

• 140 × BreadBoard Jumper Kit 140pcs Solderless Cable Wire for Prototyping

Frequently Asked Questions

• Are these jumper wires compatible with standard solderless breadboards?
  Yes, they fit perfectly into standard 2.54mm (0.1-inch) pitch breadboard tie points.
• Can I use these wires directly with an Arduino Uno?
  Yes, you can insert the stripped ends into both the breadboard and the female header sockets of an Arduino board.
• Do they work with Raspberry Pi GPIO pins?
  No, these are bare solid-core wires and are not suited for sliding over bare male header pins; use female-to-female or female-to-male jumpers instead.
• Are these compatible with MB102 breadboard power supply modules?
  Yes, they are ideal for cleanly routing 5V or 3.3V power from the MB102 rails directly to your ICs and sensors.
• What is the maximum voltage these jumper wires can handle?
  They can safely handle standard prototyping voltages up to 36V DC.
• How much current can pass through these solid core wires?
  They are designed for low-power signal routing and should generally be kept under 1.5 to 2 Amps to prevent the wire and breadboard from heating up.
• Can I use these jumpers for 220V AC mains projects?
  No, breadboards and these jumper wires are strictly for low-voltage DC prototyping and are extremely dangerous if used with AC mains.
• What is the wire gauge of these breadboard jumpers?
  These jumpers are typically made of 22 AWG solid core copper wire, which is the industry standard for breadboard insertion.
• Do I need to strip the ends before using them?
  No, all 140 pieces come pre-stripped and pre-bent at 90-degree angles for immediate, hassle-free insertion.
• How do I choose the right length of wire for my circuit?
  Select a length from the organizer box that spans the exact distance between your connection points so the insulated part lays perfectly flat against the board.
• Do these jumper wires affect the code running on my microcontroller?
  No, they are passive electrical conductors and do not interact with your software logic in any way.
• Are there digital design tools to plan my jumper wire layout before building?
  Yes, software like Fritzing allows you to visually map out colored U-shape wire routes on a virtual breadboard before physical assembly.
