The nRF24 has 5V tolearnt IOs, the RFM69 hasn't.
Too bad it doesn't have any level converters built in to make it completely compatible to nRF24.
Apart from that, nice work! ;-)
Oh, you are right. I will edit the description. My "prerequisites" - overall for battery powered sensors node - is to have the node at 3v3 (or less). This is the reason because I never thought to level converter :)
Thank you for nice work :)
