Ultra long range wireless module for Pico

Just moved :)

I haven't personally played with them, but they look pretty interesting. Does anyone have a link to a decent explanation of what 'LoRa' is?

Actually making code work with them looks pretty easy too. There's the code here and once readRegister and writeRegister functions have been re-written in JavaScript (they're almost one-liners) the rest of the code for sending and receiving is basically copy+paste.

Hopefully someone will make a module for it....
