Funny thing, I just fried two RP2040 yesterday in a attempt to build my own split mechanical keyboard (corne by foostan: https://github.com/foostan/crkbd/blob/main/docs/corne-cherry/v3/buildguide_en.md ).

In my defence, used pro micro rp2040 because it looked compatible enough with atmel based pro micro boards, and there's a firmware for rp2040 at QMK project.
