“Part way through testing these, but so far it's looking good. I'm using Nano 33 BLE as the controller and the LowPowerLabs RF69 library. This module includes a 3.3V power regulator so you can use 5V as the supply on VIN - I currently have it connected to VUSB on the Nano (which also requires a tiny solder bridge). While it is not essential to connect the module's EN pin, you must connect and use the others, including the RST pin. Make sure your sketch sets the output pin connected to RST before calling radio.initialize().”
