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! and works great with an Arduino (using the RTC library), CircuitPython, Raspberry Pi, or similar single board Linux computer
To make life easier so you can focus on your important work, they’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. Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!). They’ve also included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder!
Please 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.
