I2C RTC DS1307 AT24C32 Real Time Clock Module for Arduino Uno AVR ARM PIC T5

 This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC, and works best with 5V-based chips such as the Arduino.

The module comes fully assembled and pre-programmed with a time. You have to reset the module and set your own time. The DS1307 is accessed via the I2C protocol.
