This is a custom designed module for the DS1307 Real Time Clock. The module comes fully assembled. The DS1307 is accessed via the I2C protocol. We've written a test-bed to program the modules. This test-bed code should give you some insight on how to interface the module to any microcontroller using our example software I2C and BCD routines.



  • Two wire I2C interface
  • Hour : Minutes : Seconds AM/PM
  • Day Month, Date - Year
  • Leap year compensation
  • Accurate calendar up to year 2100
  • Battery backup included
  • 1Hz output pin
  • 56 Bytes of Non-volatile memory available to user


You'll need a CR2032 battery to run this module.
