This battery-backed real-time clock (RTC) keeps your Raspberry Pi projects accurate even if power is lost. Ideal for data-logging, clock-building, NTP servers, time-stamping, timers, and alarms.Equipped with a genuine DS3231 RTC, it integrates seamlessly with Raspberry Pi and benefits from native kernel support. A datasheet reveals the DS3231's reputation as an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal."This RTC outperforms others thanks to its internal crystal and compensating temperature sensor, which ensures minimal time drift by adjusting clock ticks. Our RTC guarantees precision with 100% genuine Maxim DS3231 chips.Compatible with any Raspberry Pi, including Pi 1 to Pi Zero, the fully assembled PCB connects easily to GPIO pins—no soldering needed. It keeps time for 5 years or more.Note: CR1220 coin cell battery not included; purchasing a battery is recommended for use with this product. https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-11-03 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-11-15 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-11-20 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-12-03 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-12-14 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2025-12-20 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-01-07 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-01-24 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-01-26 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-01-29 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-02-03 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-02-11 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-02-17 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-03-04 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-03-13 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-03-25 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-03-27 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-04-08 https://elecena.pl/product/29477993/adafruit-pirtc-precise-ds3231-real-time-clock-for-raspberry-pi 2026-04-13
