Thanks for that Ioannis - I think 3.3v is the best option here.

I would love given time to learn how to send data with the LoRa module and pic but that's for the future and a lot more learning my end (end of Summer/Autumn/Winter project).

What I am after here, is to use the Tx/Rx as a switch at about 350m range so question:

Am I right in assuming that (once paired) a state change on say Input pin1 on the Tx would be reflected as Output on pin1 on the receiver (acting as a simple switch in effect) or is that far to simple?

what you have is a lora long distance two way packet radio system that transmits the entire device state each time any input pin changes
to paired receiver constrained by the tx transmission time, that time is between 55 and 1002 mS depending on mode.
its not some cheap OOK thing
Hi Richard - I appreciate that, its a pretty suffisticated and versatile piece of kit, I have a lot of learning to do before I can do it justice but as I say above, right now to get it to operate at 350m as a mirrored switch is all I'm after.
