Notes
An open DIY HAT design for a Raspberry Pi Zero host with meshtasticd configuration. The schematic includes an Ebyte SX1262 radio module, a separate RF front-end and a GNSS receiver; the host, antennas and software configuration are assembled separately. The FEM data-sheet power figure describes its evaluation hardware, not this HAT. Designed by wehooper4.
