40-Pin Dupont Jumper Wire Ribbon Cable (2.54mm Pitch) – M-M / M-F / F-F for Arduino & Prototyping

Build, Prototype, and Connect Without Soldering

Stop struggling with loose connections, bulky wiring, or short circuits. Our 40-Pin Dupont Jumper Wire Ribbon Cables are the essential backbone for every electronics workstation, maker lab, and classroom. Whether you are wiring a rapid breadboard prototype, interfacing sensors with an Arduino, or routing GPIO pins from a Raspberry Pi, these cables deliver secure, low-resistance, solderless connections every time.

Each 40-conductor ribbon can be used as a wide bus or easily peeled apart into individual leads or custom harnesses (e.g., 2-pin for power, 3-pin for servos, 4-pin for I2C).

Available Connector Types: Choose Your Build

• Male to Male (M-M): The standard breadboard essential. Both ends feature solid 2.54 mm pins designed to plug directly into solderless breadboards, female development board headers (like Arduino Uno/Mega), and test points.

• Male to Female (M-F): The ultimate module bridge. Connect breakout boards, sensors, and displays with male pins directly to breadboard rails or controller headers without needing intermediate adapters.

• Female to Female (F-F): Ideal for board-to-board and compact enclosure wiring. Directly links male-header devices, Raspberry Pi 40-pin GPIOs, and relay boards with zero breadboard required.

• Combo Pack (120 Pcs Total): Get all 3 styles (1x M-M, 1x M-F, 1x F-F) so you are prepared for any circuit design.

Why Makers & Engineers Choose These Cables

• Standard 2.54 mm (0.1") Pitch: 100% compatible with breadboards, perfboards, DuPont housings, and standard microcontroller pin headers.

• Tear-Apart Modular Ribbon: Easily separate leads to create custom multi-pin cable harnesses (2-pin, 4-pin, 8-pin, etc.) to keep builds neat and organized.

• 10-Color Repeating Trace: Bright, distinct color coding streamlines wire tracing, simplifies troubleshooting, and prevents reversed polarities.

• Tight Retention & Low Resistance: Built with durable spring clips and plated contacts that resist vibration and ensure zero signal dropouts in DIY robotics and embedded systems.
