Description

Module with a precise real time clock (RTC) DS3232, 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 DS3232 accuracy remains at ± 3.5ppm (± 0.3024 seconds/day). It is equipped with 236Byte SRAM storage inside, enabling it to store data at an 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 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.
