This is the SparkFun Real Time Clock (RTC) Module, this little breakout that uses the DS1307 to keep track of the current year, month, day as well as the current time. The module comes fully assembled and includes 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.
The DS1307 RTC is accessed via the I2C 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 I2C and BCD routines.
This rev of the Real Time Clock module finally adds I2C resistors and a larger battery pad to fix the problems with the battery shorting to the board.

這是SparkFun實時時鐘(RTC)模塊,它使用DS1307來跟踪當前的年,月,日以及當前的時間的這個小突破。該模塊在出廠前已組裝並包括將無需外接5V電源運行RTC最少9年(17歲典型值)的小CR1225鈕扣鋰電池。
該DS1307 RTC通過I 2 C協議訪問。我們已經寫了一個試驗台的模塊編程,該代碼應該給你如何使用我們的示例軟件模塊接口對任何單片機上的一些見解I 2 C和BCD例程。
實時時鐘模塊的這種轉終於增加了I 2 C電阻和更大的電池板來解決與電池短路的電路板的問題。
