DS3231 AT24C32 IIC Precision RTC Real Time Clock with battery

This is a module made using DS3231 RTC and AT24C32 EEPROM. DS3231 is an extremely accurate, low cost I2C RTC with integrated temperature compensated crystal oscillator. It also has a built in comparator which monitors the status of VCC to detect power failures and to automatically switch to backup power supply. It is extremely accurate when compared to commonly used DS1307 RTC.  AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each. This gives you 32Kb of non-volatile memory for your projects. This module can be easily interfaced with Arduino Boards, Raspberry Pi and all Microcontrollers.
