About this board
Section titled “About this board”The RP2040 in the XIAO footprint, with an on-board RGB LED — which is why this board’s examples are about colour rather than about a single blinking pin.
The chip is the same one in the Pico, so RP2040 code ports across; what changes is how many pins come out, and the map below is the authority on that.
