Thankyou for the reply,
think its probably best if i order lipo powered board.

That post was talking about an older revision of the processor board. The +/- you've found are correct and meant for any battery about 3-4v, ie most lithium cells. Keep in mind your coin cell board does not have the charger on it, and there's no under-voltage protection- our cells have that built in, so make sure you have something in place.

Thanks,
Ben

Hello, newbie to arduino and tiny circuits. Ordered the processor board with coin, is it possible to connect lipo battery to the 2 pins labelled + - (next to on/off) switch.
Read in a post from 2014 that there is post saying gnd & + near main connector, but my tired old eyes cant see it.
Any help appreciated
