Talking of RP2040-based projects, here’s Cytron with its $10 Maker Pi RP2040. Unlike the other Pico-clones this goes for its own robot-targeting 88x64mm form factor. With two motor terminals, four servo ports, seven I/O grove ports, power and reset switches, three push buttons and li-ion battery port it’s ready to rock. See http://bit.ly/lxf278cytron.
Ready to robot! (robot not included).
