The AZDelivery RTC module with DS3231 chipset is not only characterized by its high-precision clock crystal, there is also a measurement of the temperature every minute to adjust the oscillator for correction purposes. Thanks to the supplied button cell and integrated EEPROM, the time is maintained even in the event of a power failure.
Wiring is very easy due to the used I2C bus and the IIC address can be changed of course. An additional output for the 32kHz signal is also available and can be activated via a register. The RTC is downward compatible and can also be used with the library for the DS1302.
- The Real-Time Clock provides programmable time-of-day alarms and a calendar that can be set to a square wave output. Address and data are transmitted serially via a bidirectional I2C bus.
- The module keeps track of time even when not powered. It has a built-in 3 V battery that constantly updates the time.
- The integrated oscillator improves the long-term accuracy of the module.

Built -in battery
Thanks to the built-in battery, the time continues to be stored even if the supply voltage fails. Thus, the implementation of the date taking into account leap years up to the year 2100 is also allowed.
