DS3231 RTC Module Precise Real Time Clock I2C AT24C32

The DS3231 RTC Module is a high-accuracy real-time clock (RTC) designed for precise timekeeping in embedded systems. Powered by the DS3231 chip, it features integrated temperature-compensated crystal oscillator (TCXO) and crystal, enabling accuracy of ±2 ppm (approx. ±1 minute per year).

This module includes an I²C interface, making it easy to connect with microcontrollers like Arduino, Raspberry Pi, ESP32, and others. It comes with an onboard AT24C32 EEPROM (32Kb = 4KB), ideal for storing additional user data such as configuration settings or log entries.

With a CR2032 battery holder, the DS3231 maintains accurate timekeeping even during power loss, making it a reliable choice for clocks, data loggers, alarms, and automation systems.
