DS1307 RTC Real Time Clock Module with CR2025 Cell

DS1307 Module is a real-time clock module with 32kHz and has an onboard battery backup. This module provides seconds, minutes, hours, date, week and year with leap-year compensation up to 2100. It is a small size module that’s why it is easy to plug in even on a breadboard. It has the functionality to set in 24 hours and 12 hours. It is a real time clock module so after removing the power also it sore the real-time and whenever power is given, it starts with real time. Module is compatible with microprocessors and Arduino.
