The module comes fully assembled and \u003cstrong\u003eincludes\u003c\/strong\u003e a small CR1225 Lithium coin cell battery that will run the RTC for a minimum of 9 years (17 years typical) without an external 5V power supply.\u003c\/p\u003e\n\u003cp\u003eThe DS1307 RTC is accessed via the I\u003csup\u003e2\u003c\/sup\u003eC protocol. We've written a test-bed to program the modules, this code should give you some insight on how to interface the module to any microcontroller using our example software I\u003csup\u003e2\u003c\/sup\u003eC and BCD routines.\u003c\/p\u003e\n\u003cp\u003eThis rev of the Real-Time Clock module finally adds I\u003csup\u003e2\u003c\/sup\u003eC resistors and a larger battery pad to fix the problems with the battery shorting to the board.\u003c\/p\u003e\nGet Started with the RTC Module Hookup Guide\u0026lt;\u0026gt;\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003eLithium Battery Shipping:\u003c\/strong\u003e\u003c\/span\u003e Due to courier restrictions, this product can only be shipped within the United Kingdom.
