I’m assembling my ScrabblePad board and before I get too far and have to desolder 225 switches, I’d like to double check some stuff. There’s a square pad that’s for an microSD card holder that I know I don’t need to worry about, but there’s pads labeled PA0 to PA7, R1, R2, and something that looks like it might be for a TRS or TRRS jack. Do I need to worry about any of those? And I assume the Teensy++2.0 sits with the reset button accessible.
Update: Never mind. All those things are bonus features and aren’t needed for regular use.
