5a-75b V8.0: Add power supply details, and bidir IO mod information #91

Closed polprog closed 2 years ago

I reverse engineered the power supply scheme of the 5a-75b V8.0 after I was forced to find out what buck controller is being used (I blew one up by applying 8V at the power input).

Credits for the bidirectional IO modification goes to https://twitter.com/claude1079/status/1231194849350647808, they have a different version of the board but I tested it working on mine.
