There is a new board from Google called the Coral Dev Board Mini with the 40-pin GPIO headers.
The coral board has very powerful AI on board and I managed to get docker working on it also. It has 2GB RAM and is a major step up from the raspberry pi0 with onboard Coral TPU presented as a USB device

It would be lovely if someone got the enviro+ hat working on it instead of solely a measly raspberry pi0 or equivalent
