The DS3231 I2C precision clock module is suitable for projects that need accurate timekeeping capabilities. Typical applications include clocks and data logging devices.
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 2.3 V to 5.5 V and it also features battery backup capabilities.
The DS3231 features an integrated crystal, 2 programmable time-of-day alarms, a temperature sensor, and 32.768 kHz signal output pin.
The AT24C32 EEPROM is a 32K EEPROM that 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.
