Arduino Data Logger

Features 
- Material: durable hard PCB board and plastic. 
- 100% brand new and high quality Data Logger Module Data Recorder Data Logging Shield V1.0. 
- 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 the 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 soldering connectors, circuitry or sensors. 
- Built-in 3.3V regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run 
- Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADKMega R3 or higher. nbsp; ADKMega R2 or lower are not supported.
