RTC DS1302 Arduino real-time clock module

The Real Time Clock (RTC) module based on the DS1302 chip is a functional device designed to read time and date with a precision of 1 second. The calendar is programmed up to 2,100 years. With a lithium battery for power backup, it eliminates the risk of data loss during power failure. The standard 2.54mm goldpin connector and I2C interface allow integration with modules such as Arduino. This is a practical solution for time synchronisation in electronic devices. Specification:
