DS3231SN - AT24C32 - Extreamly accurate RTC module - without Battery - Internal TCXO

This peripheral module with DS3231 RTC chip on board. DS3231 is an extremenly accurate time keeping chip by maxim integrated. It owes it's high accuracy to an internal temperature compensated crystal oscillator a.k.a TCXO. Normal RTC chip with external crystal are not that accurate as the crystal frequency varies with the change in temperature. This RTC module promises high accuracy +/- 2PPM at a temperature range of 0-40 degree celcius.

Standard I2C interface and registers to keep counts of seconds, minutes, hours, date of the month, month, day of the Week, and year, with Leap-Year Compensation Valid Up to 2100. This low cost module can be used to design your next digital clock project with a promise of showing highly accurate time.
