Notes

1W Raspberry Pi HAT radio configuration, driven by a Linux host running meshtasticd. It uses E22-900M30S; the 2 W version adds a 902–926 MHz band-pass filter and IPEX output. The maker marks this design superseded by Zebra Hat and says US use is Part 97 amateur radio only; it is not certified for unlicensed use. Designed by wehooper4.
