A precise real-time clock module - RTC, designed for Raspberry Pi series computers. It is based on the DS3231 system, which has been connected to a battery that supports its operation in the event of a main power failure. Communication with the RTC clock takes place via the I2C interface.
The DS3231 system is a complete RTC clock, which is distinguished by high precision in time measurement. Excellent parameters were obtained by integrating a quartz resonator in the structure of the system and using temperature compensation. There is a socket for a CR1220 battery on the board, which allows the clock to operate even in the absence of main power. The supply voltage required for correct operation is in a wide range of 2.3….5.5 V.
