What board

[Jack4891]

If you use LoRa you need to specify which board you are using first. I've linked arduino's for the load side but if you are going to use a raspberry pi on the controls circuit you need to use something that can work with the nano.

MAKE SURE YOU GET A CHIP WITH SX1262/SX1263
