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 back..
This tiny RTC module is based on the clock chip DS1307 which supports the I2C protocol. It uses a Lithium cell battery (CR1225). The clock/calendar provides seconds, minutes, hours, day, date,month, and year information. The end of the month date is automatically adjusted for months with fewer than ..
