DS3231 I2C RTC Real Time Clock Module

DS3231 is an I2C integrated very precision real-time clock (RTC) Module. The module has an integrated temperature-compensated crystal oscillator and two alarm clock. The battery is given on a device that keeps module running while external power is absent and maintains accurate timekeeping. The device can work in both 12 Hr and 21 Hr format finding the GPS application.
