Cheapest meshtastic board (for me);

Using a esp32-c3 and sx1276 Or sx1262, rn im waiting for the pcb for the sx1276, once everything works ill also make the sx1262 code.

it has a charging cuircuit, charging at 500ma. switch that disconnects the battery, device will be fully on when charging unless ill add a deep sleep thing, may do.

i wont explain what "meshtastic" is, just click the top link

Comes out to ~£4 / board (exc. screen, gps. & pcb if you dont order 20, or other stuff with it)
