This is a unique SparkFun product! These 12 - foot long jumper wires have female - to - female terminations. You can use them to connect from any male header on any board. Multiple jumpers can be placed side by side on a 0.1 - inch header. They come in five packs of twenty jumpers (with the colors shown), making a total of 100 jumpers. We use these wires everywhere! They're perfect for breadboards, Arduinos, and any 0.1 - inch pitch prototyping board.

Using these jumper wires is a breeze. First, identify the male header on your board where you want to make a connection. Then, simply plug one end of the female - to - female jumper wire into the male header. If you need multiple connections, you can place the jumpers next to each other on a 0.1 - inch header. These wires work great with breadboards, Arduinos, and other prototyping boards. When using them, be gentle when plugging and unplugging to avoid damaging the wires or the headers. To maintain these wires, keep them in a dry place. If they get dirty, you can use a soft, dry cloth to clean them. With proper use and care, these jumper wires will serve you well for a long time.
