DS3231 Real Time Clock Module 3.3V 5V Precise for Raspberry Pi

DS3231 Real Time Clock Module 3.3V 5V Precise for Raspberry Pi 

The DS3231 RTC Module is a highly accurate real-time clock module that keeps track of seconds, minutes, hours, day, date, month, and year.
It is built around the DS3231 temperature-compensated crystal oscillator (TCXO), providing extremely stable timekeeping with very low drift.
The module supports both 3.3V and 5V, making it compatible with Raspberry Pi, Arduino, ESP8266, ESP32, STM32, and other microcontrollers.
It also includes an onboard CR2032 battery holder, ensuring continuous timekeeping even when the main system is powered off.
