A DS3231 High-Precision RTC (Real-Time Clock) Module is a low-cost, extremely accurate I2C real-time clock board featuring an integrated Temperature-Compensated Crystal Oscillator (TCXO) and internal crystal. It maintains precise timekeeping—tracking seconds, minutes, hours, day, date, month, and year with leap-year compensation—even when main circuit power is disconnected, thanks to its onboard CR2032 coin-cell battery backup holder. The module also integrates an AT24C32 EEPROM chip for non-volatile data storage and an onboard temperature sensor that actively corrects crystal frequency drift across operating temperatures.

This product is featured by Famephase Electronic Accessories as an essential module for time-stamping data loggers, digital clocks, automated scheduling systems, and micro-controller projects requiring continuous, drift-free timekeeping.
