Description

Description:
The PCF8523 is simple and cost effective, but not a high-precision device. It can lose or win up to 2 seconds per day. For a highly precise, temperature-compensated alternative, please check the DS3231 Precision RTC. If you need a DS1307 for compatibility reasons, check out our DS1307 RTC breakout. This is a great battery operated real-time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed or when power is lost. Perfect for dataloging, clock making, time stamps, timers and alarms etc. Equipped with PCF8523 RTC - it can be powered by 3.3V or 5V power & logic.
Note: This product does not come with a CR1220 button battery. We recommend you buy a button cell to use this product.
