Thank you. This is a full circuitboard with GPS+battery+lora+CPU+oled screen for $30. So I'm not trying to compete with a $15 radio devboard that someone has to solder into their project, but more something that 'just works'. And open source, for fun, so not selling it at all ;-)

Maybe you could persuade M5Stack to do a version of hardware that suits.

Looks like maybe they do already for $40 if you combine a base and LORA unit -
