This adapter allows you to connect a barrel jack connector to bare wires. One end has soldering terminals and the other has a 5.5×2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel jack on an Arduino or a development board, this might be the simple solution.
Also, the same barrel jack can be used to connect a 9V battery cap and create a simple solution for hobby electronics
