Here’s a handy Arduino shield we’ve had a lot of people looking for a dedicated and well-designed data logging shield. We worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize. The Data Logger module Logging Shield data Recorder Shield also comes with great documentation and libraries. SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card. It also equips a Real Time clock (RTC) which keeps the time going even when the Arduino is unplugged. And, the most important the battery backup lasts for years. Cool!!! Included libraries and example code for both SD and RTC mean you can get going quickly Prototyping area for soldering connectors, circuitry or sensors. The Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run. This module is compatible with Arduino Uno, to buy it click on the name below   Features : Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher.
