40 Pin Male-to-Female Dupont Jumper Wires 20cm

Build and modify circuits faster with this 40 Pin Male-to-Female Dupont Jumper Wire set, designed for solderless electronics prototyping and quick module-to-board connections. The pack includes 40 individual 20cm jumper cables, each terminated with a male pin on one side and a female Dupont connector on the other. This makes it especially useful when you need to connect a sensor module, relay board, display, motor driver or breakout board with male header pins to an Arduino, Raspberry Pi, ESP8266, ESP32, STM32 board or a standard solderless breadboard. The 2.54mm Dupont connector format is the most common pitch used in hobby electronics, embedded development boards and PCB pin headers. The female end can plug onto standard male header pins, while the male end can be inserted into breadboard holes or female header sockets. Because the wires are 20cm long, they provide enough reach for clean bench-top wiring without creating excessive clutter in compact projects. These male-to-female jumper cables are supplied as a 40-wire strip and can be used together as a ribbon-style connector or separated into individual wires as required. They are suitable for low-voltage DC prototyping, logic signals, sensor wiring, power distribution for small modules and temporary testing during circuit development. No soldering, crimping or special tools are required, making them beginner-friendly while still being essential for labs, makers, robotics students and repair technicians. What is in the box: 1 set of 40 pieces, 20cm Male-to-Female Dupont jumper wires. Pin note: male pin on one end, female socket on the other; compatible with standard 2.54mm breadboard and header spacing. These wires are intended for prototyping and low-current electronics use, not for mains voltage or high-power loads.
