Product Description
These Male-to-Female Dupont Jumper Wires are a fundamental staple for any electronics workbench, prototyping lab, or circuit testing setup. This ribbon cable contains 40 individual, multi-colored jumper lines molded together in a flat, peelable ribbon structure. You can easily separate them into individual strands or smaller multi-pin bundles (such as 2-pin, 4-pin, or 8-pin blocks) depending on your exact sensor module or microcontroller layout needs.
With a compact length of 10cm, these cables are ideal for short-distance connections, keeping your prototyping space clean, highly organized, and free from tangled wire nests. Featuring a standard 2.54mm (0.1″) pitch male pin connector on one end and a matching female header connector on the other, they serve as the perfect bridge to extend connections or link microcontrollers to development boards and breakout sensors.
⚠️ Handling Tip: When disconnecting jumper cables from a pin header, always pull directly from the plastic connector housing rather than tugging on the flexible wire insulation. Pulling on the wire itself can stress the internal crimped connection over time and cause intermittent signal loss.
Connection Interface
This ribbon cable features a universal, solderless connection layout:
Connector Type: Male-to-Female (M-F) terminals.
Pin Pitch: Standard 2.54mm (0.1 inch), making it fully compatible with standard breadboards, Arduino Uno/Mega boards, Raspberry Pi GPIO header pins, and breakout sensor modules.
Ribbon Structure: 40 parallel wires in 10 repeating colors for quick, visual signal tracking across complex circuits.
Applications
Module-to-Board Extension: Linking male pin headers on sensors, displays, and relay modules directly to a breadboard or microcontroller.
GPIO Prototyping: Connecting directly to the exposed male GPIO pins of a Raspberry Pi or ESP32 development board.
Compact Prototyping: Wiring ultra-tight enclosures or small robotic chassis where long wires would bunch up or catch on moving gears.
