These are exclusive SparkFun jumper wires! They're 12 feet long and have male - to - male terminations. You can use them to connect from any female header on any board. On a 0.1 - inch header, you can connect multiple jumpers side by side. The pack comes with five sets of twenty jumpers in the colors shown. These wires are super versatile! They work great with breadboards, Arduinos, and any 0.1 - inch pitch prototyping board.

Using these jumper wires is easy. First, find the female header on your board. Then, simply plug one end of the jumper wire into the female header. If you need multiple connections, you can line up the jumpers next to each other on a 0.1 - inch header. When using them with breadboards or Arduinos, just plug them in wherever you need a connection. As for maintenance, keep them in a dry place to prevent rust. Avoid bending the wires too sharply as it may break the internal conductors. Also, don't tug on the wires too hard when unplugging them to prevent damage to the connectors.
