Cheap RPI pico Macropad

A challenge I attempted by trying to make the cheapest macropad with a Pi Pico for under 4 USD. Well I achieved it and the files are here. The custom QMK firmware i developed is also attached at the project page over at esccrasci.in/cheap-macropad

The keyboard in QMK compatible and it is built like any other macropad in the market.  Included are the keycaps, the base and the tabletop holder. It uses large momentary switches. but the size will be compatible with smaller keyswitches.
