Description

The DS3231 High Precision RTC Clock Module is a highly accurate real-time clock solution featuring a temperature-compensated crystal oscillator (TCXO). Unlike older RTC modules, the DS3231 maintains precise timekeeping with minimal drift, even across temperature changes.

This module communicates via the I2C interface, making it easy to integrate with Arduino, ESP8266, ESP32, and Raspberry Pi. It includes a backup battery holder to keep time running during power loss, making it ideal for data loggers, clocks, timers, alarms, and IoT applications.
