I’ve recently gotten into .NET Gadgeteer and was wondering if you guys could help me. I’m looking for recommendations for a Real Time Clock Module. It needs to have a battery so it won’t lose the time when it’s switched off
And also any battery modules you know of. I’ve seen the one that uses 4 AA batteries, but I was wondering if there was any based on Lithium batteries? Also, are there any known problems with such modules?
