The ELEGOO 120-Piece Multicolored Dupont Wire Kit is perfect for your Arduino UNO R3, MEGA 2560 R3, and NANO projects. It includes copper-clad aluminum and PVC wires, each 8-inch long. The male and female ends are compatible with standard 0.1"(2.54mm) headers and sockets, respectively, for quick, secure connections. Reusable and easy to use, this kit is ideal for rapid prototyping, circuit testing and expansion of experimental boards. The cables can be separated into a single root as you request to do multiple connections.
