    Tiny RTC - Arduino real time clock module

    Tiny RTC module  

    This module uses the DS1307 chip, which can be used for keeping time in a very wide variety of projects. For example it can be used to add time stamps to sensor readings, display the time accurately or keep track of time even when there is no power supplied (although it will require a rechargeable CR2032 battery for this). The Tiny RTC supports the I2C protocol, which makes it very easy to interface with many microcontrollers. 
    VCC:  5V DC
    Battery (optional): CR2032
    Power consumption: <500nA (in Battery Backup Mode)
    RAM: 56 Byte, non-volatile
    Memory: 32kb EEPROM
    Dimensions: 27mm x 28mm x 8.4mm
