I also have a couple, and don’t currently intent to use Pycom firmware while they require an NDA to use their mesh firmware. It would be very cool if LoPy(x) worked with Meshtastic. All the sudden I’d have a 5 devices mesh. I’ve mentioned them in a couple threads, but afaik, nobody has it ported over.
No GPS, but they do have the advantage of usually being in-stock at places like Mouser.
