• Simple cabling via only four pins thanks to I2C interface.

Description

The AZDelivery RTC module with DS3231 chipset
is not only characterised by its high-precision clock crystal
, but 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 retained even in the event of a power failure.
Wiring is very simple due to the I2C bus
used and the IIC address can be changed naturally. 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.
Details
Cheap
For reliable display and storage of the time
Popular in the community
Many libraries and application examples available for most microcontrollers
Special features
The real-time clock offers 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 if it is 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. This allows the implementation of the date taking into account leap years up to the year 2100.
Open source libraries
Easy integration into projects (data acquisition, clock construction, timestamps, timers, alarms) thanks to ready-made open source libraries. Our real-time clocks are compatible with all current Raspberry and Arduino models.
