Tiny RTC Module DS1307 + 24C32 Memory (without battery)

Description

• Description :This battery powered clock allows you to keep reasonably accurate time even when your Arduino is powered off.  Its very useful in data logging and other time sensitive applications.The device uses I2C to communicate with your Arduino.Tiny RTC Module, for Arduino, contains a DS1307 real-time clock IC with a backup battery. It’s one of the easiest to use RTCs out there, with Arduino and other libraries or simply use I2C commands to set and retreive the time and date.  It’s very easy to use, and with our Arduino tutorial you’ll be up and running in no time.

  Along with the DS1307 real time clock, the module also has an Atmel 24C32 EEPROM chip which is handy for storing data without worrying about power loss. There is also space on the board to solder your own DS18B20 temperature sensor.
