Jumper Wire Kit (120 pcs, M-M / M-F / F-F)

The 120 pcs M-M / M-F / F-F Jumper Wire Kit is an essential breadboard wiring set for anyone building or testing electronic circuits. Each cable is approximately 20 cm long and uses standard Dupont-style 2.54 mm connectors, the common connector format used on Arduino boards, Raspberry Pi GPIO headers, ESP8266/ESP32 modules, sensor boards, relay modules, motor driver modules and standard solderless breadboards. The kit is divided into three useful connection types: 40 male-to-male jumper wires for breadboard-to-breadboard or breadboard-to-module connections, 40 male-to-female jumper wires for connecting development board pins to breadboards or modules, and 40 female-to-female jumper wires for linking pin headers between modules. The multicolour wires make it easier to separate power, ground and signal lines while debugging or documenting a project. These Dupont jumper cables are passive interconnect wires, so there is no chipset, driver or programming required. Simply plug the required ends into 2.54 mm headers or breadboard tie-points to make a temporary or reusable connection. The wires are supplied in 40-pin ribbon-style strips and can be separated into individual wires or smaller grouped cables as needed, which helps keep wiring clean in prototypes, educational kits and test setups. Typical applications include Arduino sensor experiments, Raspberry Pi GPIO wiring, breadboard power distribution, robotics projects, relay module wiring, motor driver testing, IoT prototypes and classroom electronics practice. This kit is intended for low-voltage prototyping and signal-level connections; it should not be used for mains wiring or high-current loads. In the box: 40 x male-to-male jumper wires, 40 x male-to-female jumper wires and 40 x female-to-female jumper wires, all approximately 20 cm long in assorted colours.
