The SD3031 precision real-time clock (RTC) module integrates a quartz resonator and temperature compensator to improve the module's long-term accuracy of ±3.8 ppm (±0.32832 seconds/day) at 25°C. It is equipped with 70 B of SRAM, enabling data storage with extremely low power consumption. 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 24-hour or 12-hour format with AM/PM indicator and has two built-in programmable alarms. A CR1220 battery socket is located on the board. It is powered by 3.3 V and communication is via an I2C interface. Full documentation is available on the product wiki page.
