I want to use a Pro Micro with a keyboard grid of 8x13 and the board has a few less of gpio. I think if I solder some wires directly to MC itself it might be enough... How many would I need to solder 1 or 2? TX0/RX1 can be used as GPIO, right? p.s.edit: removed "leonardo"

Reusing omitted pins in the Pro Micro board
