DS3231 w/ AT24C32 EEPROM | MINI DS3231 RTC High Precision Real-Time Clock Module

Features:

The DS3231 RTC High Precision Real-Time Clock Module is a low-cost, extremely accurate I2C real-time clock (RTC), it is more accurate than the DS1307 as this module is integrated with temperature-compensated crystal oscillator (TXCO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted.
