Yeah thats exactly what i was thinking, using a Zero 3 as a Access Point, or even a router... i will to see the wireguard bandwidth. Too bad they didnt wired the built-on 100mbits NIC to the pins.
For now, im playing with a Orange PI Zero 2W i couldt not boot armbian yet. I wanted to use a wavewhare 3.5" SPI display on it, that i have no idea of how to make it work. The 2W is it mostly compatible with RPI GPIO, SPI pins are all on the same place, even the SPI CS.
