Description Real Time Clock (RTC) DS1307 I2C Clock module
This small RTC module is based on the clock chip DS1307 which supports the I2C protocol. The RTC uses a Lithium button cell battery. This keeps the RTC counting while the voltage of the microcontroller is off. The clock / calendar provides information about seconds, minutes, hours, days, dates, months and years. Thanks to this module, your Arduino can display the correct date and time on 1 battery for up to 7 years.
