Hello,
I noticed that the TinyDuino Processor Board can include a battery holder, and I'm curious about the capacity range for CR1612-1632 batteries that can be used with it. I've seen capacities ranging from 50mAh to 137mAh.

Additionally, if I choose a processor board with a battery holder, are there still positive and ground connection holes available for connecting an external battery when not using a coin battery?
