Looking at the specs and discussion on Reddit where the Dev became hostile I'd be starting the hell away from this.
50milliwat transmitter with CD tone audio? 470+ MHz transmitter, but uses FRS frequencies?
Evening this offers had been done before.
If the Dev want hostile and bullshitting, trying to pass this off as some new thing I think they could actually sell a few of these to people that want something ready built or want to learn about LoRa.
But there is still the issue that the voice side of this will be illegal just about everywhere.
What makes voice over LoRa illegal?
Sounds like he's referring to the frequency it's operating at, but I honestly don't know enough about that kind of stuff
