Unless I'm seeing it wrong, it looks like DIO1 and Reset lines aren't connected to the M0.
I'm hoping to add an RFM95 HopeRF board to an M0 as a second radio.
Should it work without either of those pins connected ?
I'm thinking of using D10 for DIO0 and A1 for NSS.
If I really need Reset, can I just use any spare pin, or do I need a special one that is a hardware interrupt, like D3 on a Atmega328p chips.
If anyone has added a second radio successfully, it would be great to have info on how they accomplished it.
Thanks,
Jerry
