Simple adapter for RFM69H(W). You can use a RFM69H(W) radio using previous NRF24 socket.
All pins are mapped 1:1 to NRF24.
There is place (if you need) for a capacitor (reality, never used with RFM69).
You can use big gain antennas or smaller antenna (I use 5dbi on amplified radio and single coil on not-amplified).
Pay attention: NRF have PINs tolerant to 5V, RFM no. So, power and get/send data at 3v3 and not 5V. But, if you use battery nodes, probably you want use 3v3 from start :)
