Description

DS3231 is a low-cost and extremely accurate I2C real-time clock, with an integrated crystal and temperature-compensated crystal oscillator (TCXO).  DS3231 can be operated using supply voltages ranging from 2.3V to 5.5V and it also features battery backup capabilities. The DS3231 features an integrated crystal, 2 programmable time-of-day alarms, a temperature sensor, and a 32.768 kHz signal output pin. The AT24C32 32KB EEPROM can be used to add non-volatile data storage to your electronic projects and prototypes. The module also features a battery holder, allowing you to add a backup battery to ensure continuous operation after power cut-off. When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.
