The DS3231 AT24C32 Precision RTC I2C Module is a battery-backed real-time clock module that keeps accurate time and date for Arduino, Raspberry Pi, ESP32, and other microcontroller projects over the I2C interface. Built around the DS3231 RTC chip and paired with AT24C32 EEPROM, it provides reliable timekeeping even when main power is removed, with the included CR2032 battery maintaining the clock. Use this board for data loggers, alarms, clocks, timers, home automation, and IoT prototypes that need persistent timestamps and simple I2C integration.
