Male to Female Jumper Wires 20cm Pack

The Male to Female Jumper Wires 20cm Pack is one of the most useful interconnect sets for any electronics workbench. These Dupont-style jumper cables are designed for quick, solderless connections between breadboards, development boards and electronic modules that use standard 2.54mm pin headers. With a male connector on one side and a female connector on the other, they are perfect for linking a breadboard row to a sensor module, plugging into Arduino-style header sockets, or extending signals from modules such as displays, relay boards, motor drivers and communication breakouts. Each wire is approximately 20cm long, giving enough reach for compact prototypes while keeping wiring neat and manageable. The individual single-pin leads can be used separately, grouped together, or split as needed for power, ground and signal routing. Because they are reusable and easy to insert or remove, these male-to-female jumper wires are especially helpful during testing, troubleshooting, learning electronics and building temporary circuits before moving to a soldered PCB or custom harness. Use them for common DIY and educational projects such as LED experiments, sensor interfacing, IoT prototypes, robotics wiring, microcontroller programming setups, display connections and breadboard lab work. They are compatible with the widely used 2.54mm spacing found on Arduino, Raspberry Pi GPIO headers, ESP8266/ESP32 boards, Raspberry Pi Pico, STM32 development boards and many generic Indian-market modules. Package includes one pack of 40 male-to-female 20cm Dupont jumper wires. Pin note: the male end fits breadboards and female header sockets, while the female end fits standard 2.54mm male header pins. These wires are intended for low-voltage, low-current prototyping connections; for motors, heaters or other high-current loads, use appropriately rated wiring.
