DS3231 module features:

Communication: I2C interface.
Keeps time accurately, even when the module is not connected (backup battery)
Year - month - day hour : minute : second
Connection for external trigger with interval (1Hz, 4kHz, 8kHz, 32kHz)
56 Bytes Non-volatile memory
Greater precision than the DS1307
Extra memory chip: AT24C32 (32K bytes)
Built-in temperature sensor (deviation of ±3 °C)

Supplied without battery

Please note use rechargeable battery LIR2032
