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

Product Description

These Male-to-Male 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 breadboard or microcontroller layout needs.

With a compact length of 15cm, these cables are ideal for short-distance connections, keeping your prototyping space clean, highly organized, and free from tangled wire nests. Each wire features standard 2.54mm (0.1″) pitch male pin connectors securely crimped on both ends, allowing them to plug directly into standard breadboards, female headers, or sensor modules.

⚠️ Handling Tip: When disconnecting jumper cables from a breadboard or header pin, 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 Male-to-Male (M-M) pins.

• Pin Pitch: Standard 2.54mm (0.1 inch), making it fully compatible with standard breadboards, Arduino Uno/Mega boards, Raspberry Pi GPIO extension shields, and IC sockets.

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

Applications

• Solderless Breadboarding: Linking microcontroller pins directly to breadboard rows for rapid testing of components like LEDs, buttons, and ICs.

• Module-to-Module Bridging: Daisy-chaining hardware shields, logic analyzers, and development modules that share female pin footprints.

• Compact Prototyping: Wiring ultra-tight enclosures or small robotic chassis where long wires would bunch up or catch on moving gears.
