This board has an rp2350b chip on it, as well as a Lattice Semiconductor iCE40UP5K FPGA. More details of this open hardware board here: https://pico2-ice.tinyvision.ai/ Tested on a pico2-ice board with: ~/go/bin/tinygo flash -target=pico2-ice src/examples/blinky1/blinky1.go which blinks the GREEN LED (connected to GPIO0) on this board.

Reading the schematic and the rev2 board viewer: https://raw.githubusercontent.com/tinyvision-ai-inc/pico2-ice/refs/heads/main/Board/Rev2/bom/ibom.html concluded that the RP2350B GPIO pins are not labeled with these pin numbers in the silkscreen. Instead, the silkscreen refers to uses of the GPIOs or the ICE numbered pins. RP2340B devoted pins map to the A1..4 B1..4 pins on the RP PMOD connector. Also silkscreen "~0".."~6" are labeled as pins N0..N6. Signed-off-by: Tinkerer <[email protected]>

These are usually called LED_RED etc for other boards.

Can you add these pin numbers (GPIO30 etc) to a new file for the rp2350b? So they can be shared across boards with an rp2350b.
