Screw-terminal barrel plug

Description

This is a 2.1mm standard (Arduino) power plug, with screw terminals. It makes it easy to re-purpose all those spare wall-adapters in your parts box.

Just insert the wires and screw the terminals down. I would also recommend tinning the wires, if you have a soldering iron.

Be aware that the plug doesn’t really offer much strain relief. If you think the plug will find its way into an active environment – such as with bands, we’d recommmend soldering the wires to the plug, after screwing them in, and or adding a bit of hot glue or epoxy putty for strain relief.
