This RTC (Real Time Clock) module makes it very easy to keep track of time. Due to temperature compensation, the RTC is very accurate. In addition, this module also has built-in SRAM to store data that will not be lost if an optional backup battery is installed.

Note: No backup battery is included, it is available separately: Button cell 1220
