DS1302 real-time clock module with battery high-precision timing STEAM education/artificial intelligence kit

The sensor uses the DS1302 chip, which contains a real-time clock/calendar and 31 bytes of static RAM, and communicates with the microcontroller through a serial interface. The real-time clock/calendar circuit provides seconds, minutes, hours, days, weeks, months, and years of information, and the number of days in each month and leap year can be automatically adjusted. Clock operation can be determined by AM/PM indication in 24 or 12 hour format. It has the characteristics of low power consumption and high precision.
