Cherry-Compatible Keyswitch Tester

This is a simple keyswitch tester PCB for Cherry-compatible mechanical keyboard switches. It holds four keyswitches using Kailh's hotswap switch sockets and has an LED wired to each switch, providing a quick and simple way to test the actuation point of various switches. This board is powered either by a MicroUSB connector, or optionally instead via a 2 x 0.1" header connected to a 5 V power supply.

Most of this board can easily be assembled by hand, except for the MicroUSB connector which is a bit more tricky, so if soldering this by hand, you may prefer to use the header pins instead.
