16 channel board?

This looks interesting. I'm unclear which 'chinese 16 channel relay' you mean? Could you provide a link please?

Presumably, the software side would work with Adafruit Canbus Picobell and this relay board?

OK thanks. I still don't quite get how the two are connected. 16 channel is overkill for me anyway.

Would you anticipate any issues running your firmware on
