Male to Male Jumper Wire Set

The Male to Male Jumper Wire Set is an essential connectivity kit for every electronics workbench. Designed for solderless prototyping, these 20cm Dupont-style jumper cables let you make quick point-to-point connections between breadboards, development boards and modules without cutting, stripping or soldering wire. The male pin at each end fits standard breadboard tie points and 2.54mm pitch female header sockets, which makes the set suitable for Arduino, ESP32, ESP8266, Raspberry Pi interface boards, sensor modules, relay boards, motor driver inputs, LCD modules and general embedded electronics experiments. Each pack includes 40 individual male-to-male jumper leads in assorted colours, helping you organise power, ground and signal lines while debugging circuits. The 200mm length offers a practical balance: long enough to route across a breadboard or between nearby boards, yet compact enough to keep prototypes neat. These wires are passive interconnects, so they do not require drivers, libraries or configuration. Simply plug one end into a breadboard row or female header and the other end into the required test point, GPIO pin or module input. For best results, use these jumper wires for low-current prototyping, logic signals and common 3.3V or 5V breadboard circuits. They are especially useful for educational kits, robotics projects, IoT prototypes, microcontroller experiments, sensor testing and temporary repair diagnostics. The standard 2.54mm compatibility also allows easy pairing with common header pins, breakout boards and prototyping shields. In the box: 40 pieces of 20cm male-to-male jumper wires. Pin note: both ends are male Dupont-style pins, intended to plug into breadboard holes or female headers; for board-to-module connections with male headers, choose male-to-female jumper wires instead.
