This is a simple two - wire cable that's perfect for connecting boards or various other applications. It has 2 - pin JST RE connectors on both ends and is designed for standard 0.1 - inch breakaway headers. Measuring 12 inches in length, it comes with a drawing for reference.

These jumper wires are really easy to use. Just connect the two - pin JST RE connectors on both ends to your boards or whatever you're working on. They're great for quickly setting up connections between different parts. When using them, make sure the connectors fit snugly to avoid loose connections. As for maintenance, keep them in a dry place and avoid bending them too sharply, as that could damage the wires. If you need to move them around, handle them gently. And refer to the drawing that comes with them if you're not sure how to connect them properly.
