A dedicated and well-designed data logging shield for Arduino. The SD card interface works with FAT16 or FAT32 formatted cards. The 3.3 V level shifter circuitry prevents damage to your SD card. The onboard Real time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup can last for years. This shield works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported.
