Female to Female Dupont Jumper Wires (40-Pin / 15cm) | Pro Tronix

Product Description

These Female-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 component or microcontroller layout needs.

With a versatile length of 15cm, these cables provide the perfect amount of slack to reach across medium-sized layouts without creating a messy tangle of wires. Featuring standard 2.54mm (0.1″) pitch female header connectors on both ends, they are specifically designed to link directly between two boards with male pin headers, such as connecting sensor modules, OLED displays, or relay boards to a development board’s GPIO pins.

⚠️ 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: Dual Female-to-Female (F-F) terminals.

• Pin Pitch: Standard 2.54mm (0.1 inch), making it fully compatible with the male header pins found on Arduino Uno/Mega, Raspberry Pi GPIO headers, ESP32 development boards, and various sensor breakout modules.

• Ribbon Structure: 40 parallel wires in 10 repeating colors for quick, visual signal tracking across complex circuits.

Applications

• Module-to-Board Interconnects: Directly connecting dual-in-line male headers on sensors, drivers, and modules to development boards without a breadboard.

• GPIO Extension: Wiring up custom hardware extensions and peripherals to the exposed male pins of single-board computers like the Raspberry Pi or BeagleBone.

• Chassis & Panel Wiring: Connecting front-panel switches, indicator lights, or external modules to an internal driver board inside custom enclosures.
