- one ufl or one SMA on the 868 Mhz output is ok for the EU
- you don't need all the feather GPIO pins if you just want to trigger an alarm or measure a temp
minimal connections would be Rx Tx 3v Gnd to the RN2483.. and a few free lines for the sensors - a fancy board would have opposite the SMA connector an ICSP angled header (to test0 / test1) for updating the firmware
- more GPIO from the RN2483 ? .. maybe a few lines, I never used them sofar (only for a status led)
- I don't have a problem when the RN feather board is a bit wider on both sides if the mounting/header holes are still corresponding
