This is a great battery-backed real-time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for data logging, clock-building, time stamping, timers, and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!
Note: This product does not come with a CR1220 coin cell battery.
The PCF8523 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day.
Revision history:
As of Aug 30, 2017, we have updated the design to have an RC filter on the power supply to reduce accidental resetting if power drops too fast!
