“If space is a problem or if you need more flash, this is the better alternative to the Pico. The castellated holes look nice, but since the processor and some other components are on the bottom, they don't really make sense (no way to solder the tiny2040 in SMD-style to a board).
You loose one SPI-bus, but gain one ADC-pin. Also very nice: Pimoroni managed to integrate a second button and an RGB-led.”
