Real Time Clock PCF8523

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 datalogging, clock-building, time stamping, timers and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic. Works great with an Arduino using the Adafruit RTC library, with CircuitPython or with a Raspberry Pi (or similar single board linux computer).

The PCF8523 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day.
Note: This product does not come with a CR1220 coin cell battery.
