Module with a precise real time clock (RTC) DS3231, which integrates a quartz resonator and a temperature compensator, which improves the long-term accuracy of the module. From -40°C to 85°C, the DS3231 accuracy remains at ± 3.5ppm (± 0.3024 seconds/day). The clock counts seconds, minutes, hours, day of the month, month, day of the week and year with leap year compensation. It can operate in a 24-hour or 12-hour format with an AM/PM indicator and has two built-in programmable alarms. There is a CR1220 battery socket on the board. It is powered with the voltage from 3.3 V to 5.5 V, and communication takes place via the I2C interface. Full documentation is available on the product Wiki page.
