Description:
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 A-rduino using our RTC library or with a Raspberry Pi (or similar single board linux computer)
PCB & header are included
Plugs into any breadboard, or you can use wires
Two mounting holes
Note: This product does not come with a CR1220 coin cell battery. We recommend you purchase a coin cell battery to use with this
product.
The PCF8523 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. For a
high-precision, temperature compensated alternative, please check out the DS3231 precision RTC . If you need a DS1307 for
compatibility reasons, check out our DS1307 RTC breakout
