Just to let you know I am the author of the reddit thread. And yes noticing the superior WiFi support did not take long, I have collected approximately 20 different WiFi chipsets/adapters trying to find adapters supported on later images of Pwnagotchi. Resulting in nothing but total failure. Around half of those adapters work in Armbian (with monitor mode) without any interaction from myself.
I do indeed have a working image that a few people are testing and reporting good results with. It's taken a long time to get it to this state, so a couple more weeks of testing shouldn't be too much hold up.
I am also in contact with DrSchottky who is one of the maintainers of Nexmon. Who is of the opinion that Nexmon should and will work as well as it does on the Raspberry Pi (in fact better as we have an external antenna). Once I get around to spending some more time on the project. He has had it installed and working on the M2 Zero.
The last piece of the puzzle will be getting the screens working over the GPIO, but that will likely require someone with better knowledge of such things than myself, as the drop in replacement RPi.GPIO library didn't seem to work.
