Overview

• The DS1307 is a low power Full Binary (BCD) Real Time Clock (RTC) IC with 56 bytes of SVRAM that communicates through I2C Protocol.
• The IC can work from directly supply on Vcc and switch to Battery automatically when required.
•  The DS1307 is simple and easy to use but not very precise. It could lose or gain up to 4 minutes every month, but for most projects that is not a problem. However if you want a more accurate clock, check out the DS3231 Real Time Clock
