How to use
Choose wires of appropriate length and insert the connectors onto the target header pins, module pins or test points. Use the color coding to keep track of signals and routes. For breadboard use, push the wire ends into the breadboard holes or header sockets until they seat firmly. Remove or reposition wires as needed during iterative prototyping and testing.
Usage recommendations
Use the jumper cables for low-voltage signal and prototype connections only. Avoid excessive mechanical stress on soldered joints and connector pins. For permanent or high-current connections, use appropriately rated cables and soldered or crimped terminals.
