The Harvard TinyML series used these so I have a couple plus the expansion 
board to a camera for image recognition that was in their kit. Saves you a 
lot of Dupont wires :)

I bought one of these 6 years ago and it was my introduction to 
CircuitPython and ARM Cortex M0. Not a bad package to play with. 
CircuitPython can be a little friendlier that MicroPython but the last 
time I looked it didn't do interrupts. I don't think it has the decorator 
that MircoPython uses to do the weird little GPIO assembler stuff either. 

So many toys, so little time. I'm starting to miss the old toys though. 
When you dig into the guts of the Pico 2's processor it gets gnarly. 4 
cores, 2 ARM and 2 RISC-V plus all the wiring to bridge to the GPIOs. Lot 
of registers with a lot of bits is you got deep into the C stuff.
