40-Pin Jumper Wires M2M M2F F2F Breadboard Dupont Cables Arduino

40-Pin Jumper Wires – Breadboard & Arduino Dupont Cables

Build, prototype, and experiment with confidence using these versatile 40-pin jumper wires. Available in multiple lengths (10cm, 15cm, 20cm, and 30cm) and all three connector configurations — Male-to-Male (M2M), Male-to-Female (M2F), and Female-to-Female (F2F) — these cables are an essential addition to any electronics workbench or DIY kit.

Made in Mainland China.

Key Features

• Universal Compatibility: Designed to fit standard 2.54mm (0.1") pitch headers and sockets — fully compatible with Dupont connectors, Arduino boards, breadboards, PCBs, and PC motherboards.
• Three Gender Options: Male-to-Male, Male-to-Female, and Female-to-Female — cover every connection scenario in your project.
• Multiple Lengths: Choose from approximately 10cm, 15cm, 20cm, or 30cm to suit your layout perfectly.
• 40 Pins per Set: Enough wires for complex multi-connection circuits right out of the box.
• Separable Ribbon Design: Multicolored, soft, flexible ribbon cables that can be peeled apart into individual wires for precise, tidy wiring.
• Low Voltage Safe: Rated for low-voltage use (below 50V AC or 75V DC), suitable for all standard electronics prototyping.

Frequently Asked Questions

Q: What connector pitch do these jumper wires use?

A: These jumper wires use the standard 2.54mm (0.1") pitch Dupont housing connector, making them compatible with the vast majority of Arduino boards, breadboards, Raspberry Pi GPIO headers, and PCB male headers and female sockets.

Q: Can the ribbon cable be separated into individual wires?

A: Yes! The multicolored ribbon cables are fully separable — simply peel apart as many individual wires as you need. This makes it easy to keep your project neat and organized, using only the connections you require.

Q: What lengths and configurations are available?

A: These jumper wires are available in approximately 10cm, 15cm, 20cm, and 30cm lengths. You can also choose your preferred gender configuration: Male-to-Male (M2M), Male-to-Female (M2F), or Female-to-Female (F2F), giving you the flexibility to cover all breadboard and prototyping scenarios.

Q: Are these wires suitable for Arduino DIY projects?

A: Absolutely. These cables are specifically designed for Arduino, breadboard, Raspberry Pi, and general DIY electronics projects. Their low-voltage rating (below 50V AC / 75V DC) makes them safe and ideal for all standard prototyping and maker applications.
