Product 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 data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!

We've had a breakout board version of this RTC for a while, but we want to make it even easier for folks to use, so now it comes with STEMMA QT connectors for plug-and-play simplicity.

Works great with an Arduino using our 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. 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 QT breakout

To make life easier so you can focus on your important work, we've taken the sensor and put it onto a breakout PCB along with support circuitry to let you use it with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/ Metro328) logic levels.

Comes as a fully assembled and tested breakout plus a small piece of header. You can solder header in to plug it into a breadboard, or solder wires directly.
