TheDS1307 RTC Module is a low-power real-time clock designed for precise timekeeping. It keeps track of seconds, minutes, hours, day, date, month, and year, with automatic leap-year correction. The module communicates using the I2C interface, making it compatible with microcontrollers like Arduino, Raspberry Pi, and ESP8266. Additionally, it features an AT24C32 EEPROM for extra data storage and includes a CR2032 battery to retain timekeeping even when power is lost. This module is also available without battery.

Features of DS1307 RTC Module:

1. DS1307 RTC chip for real-time clock functionality.
2. I2C interface for easy communication with microcontrollers.
3. AT24C32 EEPROM (32Kbit) for additional non-volatile data storage.
4. Keeps track of time even when the system is powered off.
5. Stores seconds, minutes, hours, day, date, month, and year with leap-year compensation.
6. Supports both 12-hour and 24-hour formats.
