DS3231 Module is a Bread Board friendly extremely precise I2C real-time clock Module. This module is made using DS3231 RTC and AT24C32 EEPROM integrated with a temperature-compensated crystal oscillator. It also has a built-in comparator to monitor the status of VCC for power failure detection and automatic backup power supply switch. AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each, giving you 32Kb of non-volatile memory for your projects. It can be easily interfaced with Arduino Boards, Raspberry Pi, and all microcontrollers.
