Using this adapter is super easy. First, find the board with a DC jack that you want to connect the battery pack or wired power supply to. Then, take the end with the 2.1mm DC plug and insert it into the DC jack on the board. Next, connect your battery pack or wired power supply to the screw terminal block on the other end. Make sure to match the positive and negative connections according to the labels on the terminals. When using, avoid exposing the adapter to extreme temperatures or moisture. To keep it in good condition, clean it gently with a dry cloth every once in a while. That's all you need to know to use and maintain this handy adapter.
