Hi, I’m making the two-pico version, and planning on using four or five pedal switches wired to GPIO pins. Should they go to board A or board B? Also, I read somewhere on this forum that GPIO 0 and 1 are for debugging and shouldn’t be used for inputs. Are there other GPIO pins I should avoid? Thanks.
Wire your switches to the “A” Pico.
GPIO 2 and 3 are also used for something else, but the rest should be OK.
