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

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

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