Radically low-cost, can't disagree :)

PCB files are actually available: https://github.com/CapibaraZero/resources/tree/main/PCB/

OTOH it's nice to be able to literally see every part, and how they are connected.

Does anyone know what the legality of these are? Can you get in trouble just for purchasing things like flipper zero? Or just for using them in some way?
