- SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card
- Real time clock (RTC) keeps the time going even when for Arduino is unplugged. The battery backup lasts for years
- Included libraries and example code for both SD and RTC mean you can get going quickly Prototyping area for solderingconnectors, circuitry or sensors.
- Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
- Works for Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported
