1.Here we have an Data logging shield for your arduino. This unit comes fully assembled and ready to use.
Now you can easily save data to a FAT16 or FAT32 formatted SD card and the included real time clock
(battery included !) will timestamp all your data with the current time. 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.
SD card interface works with FAT16 or FAT32 formatted cards.
2.3.3v level shifter circuitry prevents damage to your SD card
3.Real time clock (RTC) keeps the time going even when the Arduino is unplugged.
4.Battery backup lasts for years
5.Prototyping area for soldering connectors, circuitry or sensors.
