SparkFun Real Time Clock Module

The SparkFun Real Time Clock (RTC) Module is a compact and highly functional device that utilizes the DS1307 to accurately track the current year, month, day, and time. This module comes fully assembled and includes a CR1225 Lithium coin cell battery that can power the RTC for a minimum of 9 years, and up to 17 years without the need for an external 5V power supply.

The RTC module is accessed via the I²C protocol. SparkFun has developed a test-bed to program the modules, providing insight on how to interface the module with any microcontroller using example software I²C and BCD routines.

This version of the RTC module introduces I²C resistors and a larger battery pad, effectively addressing previous issues with the battery shorting to the board.

The SparkFun RTC Module boasts an array of features including a two-wire I²C interface, hour, minutes, seconds AM/PM, day, month, date, year, leap year compensation, accurate calendar up to year 2100, battery backup, 1Hz output pin, 56 Bytes of non-volatile memory available to the user, and 0x68 I²C Address. The module measures a compact 20x20mm.

Whether you're a hobbyist or a professional, the SparkFun RTC Module is a versatile tool that can be used in a variety of applications. It's perfect for time-sensitive projects or any application where accurate time tracking is essential. The module's small size and low power consumption make it ideal for portable and battery-powered projects.

In addition to its impressive functionality, the SparkFun RTC Module is also incredibly user-friendly. The inclusion of I²C resistors and a larger battery pad make the module easy to use and less prone to issues, ensuring a seamless experience for the user.

In conclusion, the SparkFun RTC Module is a compact, highly functional, and user-friendly device that is perfect for any application requiring accurate time tracking. Its impressive array of features and long battery life make it a valuable addition to any project.
