These adapters are super-handy for wiring up your project to a DC barrel jack power source. Your 2.1mm barrel jack plugs into one end, and the other side has terminal blocks for attaching wires.
The terminals block has the polarity labelled on them, which assumes a centre-positive tip (most barrel jack PSUs are centre-positive, but always check first!)
This is ideal for breaking out a 5V power supply for powering LED strips, NeoPixels and more!
