This is a great battery-backed real time clock (RTC) that allows your Raspberry Pi project to keep track of time if the power is lost. Perfect for data-logging, clock-building, time-stamping, timers and alarms, etc. Equipped with PCF8523 RTC, it works great with the Raspberry Pi and has native kernel support. https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2021-04-06 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2021-08-13 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2021-08-19 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-08-18 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-09-01 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-10-14 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-10-21 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-11-01 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-11-20 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2022-12-01 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-02-14 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-02-28 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-07 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-13 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-14 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-15 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-16 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2023-03-17 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2024-07-10 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2024-08-04 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2024-11-26 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2024-12-03 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-02-22 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-03-03 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-04-26 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-05-12 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-08-08 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2025-08-21 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2026-01-30 https://elecena.pl/product/17499205/adafruit-pirtc-pcf8523-real-time-clock-for-raspberry-pi 2026-02-16
