Male to Male Jumper Wires (Pin to Pin) – 10cm / 20cm / 30cm Rainbow Dupont Cables for Breadboard

Overview

The Male to Male (M-M) Jumper Wire is the fundamental building block of any DIY electronics project. Featuring a solid 2.54mm pin on both ends, these cables are specifically designed to plug directly into breadboards, female headers, or IC sockets. Sold as a 40-pin “Rainbow” ribbon, these Pin-to-Pin wires can be used as a wide bus for data or peeled into individual strands for power and ground connections.

Key Features

• Breadboard Optimized: Pins are designed for a snug, secure fit in standard 830-point and 400-point breadboards.

• Easy Organization: The 10-color rainbow sequence allows you to color-code your circuits (e.g., Red for 5V, Black for GND, Yellow for Data).

• Peel-to-Size: Need an 8-pin ribbon for a sensor? Just peel it off! No scissors or wire strippers required.

• Durable Construction: Molded housing ensures the pins won’t snap off easily during repeated insertions.

Variation Guide: Which length is right for you?

Length	Best Used For
10cm (Short)	Making small “jumpers” between components on a single breadboard. Keeps the circuit looking clean and professional.
20cm (Standard)	Connecting an Arduino Uno to a breadboard. The most versatile length for 99% of student projects.
30cm (Long)	Perfect for connecting two separate breadboards or bridging power across large robotic chassis.
