The RTC Board
Introduction
Based on the low cost easy to use Real Time Clock IC MCP7940, this board offers a simple breakout for the part taking care of the sensitive crystal connections (probably wouldn't work very accurately on a breadboard). The 'N' version is with a battery backup, where the 'M' is not. Either part can be used.... if the N version is placed, then the board also provides a CR1220 battery holder, which should work with 12 or 12.5mm batteries.
