@michcia @kaia The first Zero would be a nice SBC choice to build stuff like an environmental sensor station, smart regulators and stuff, given the GPIO pins. The Zero 2 is way too expensive for that purpose.
With 30$/€ the Zero 2 is basically inside the limbo, not being a full SBC with the necessary I/O but also too expensive for smaller stuff unless you're rich enough to just spend hundreds on just a few of them.
