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

DIO1 is not connected to anything. It's fairly easy to solder a thin wire from any radio pin to a Moteino pin header if you really need to.
The second radio idea ... i once entertained that but it complicates a lot of things for a rather obscure purpose and i'd rather not be on the support end of all that.
You can connect multiple SPI devices to a board, as long as you have spare CS pins and can handle their setup in code.
