Produktbeskrivning:

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 our RTC library, with CircuitPython 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
  • Will keep time for 5 years or more

Note: This product does not come with a CR1220 coin cell battery.

NOTE: 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.
