DS1307 RTC Real Time Clock Module
DS1307 RTC Real Time Clock Module with real time clock DS1307 and battery back-up. It allows you to read time in the form of hours, minutes and seconds and dates: month, day, year. It has 32 kb EEPROM memory. The communication interface is the I2C bus (lines SDA and SCL) , the data refresh rate is 1 Hz (1 second).
The 5 V supply voltage is connected tobthe pin marked with the same symbol. The I2C bus should be connected to the SCL terminals - clock line and SDA - data line. Pin SQ is the output of a rectangular signal with the selected frequency . GND is the ground of the system.
