Adafruit Assembled Data Logging Shield for Arduino

A well designed data logging shield for Arduino. This shield is "R3" compatible so you can use it with just about any Arduino or compatible. You can be up and running with it in less than 15 minutes - saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program. 

• 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.
• Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run

With this new version you can use it with:

• Arduino UNO or ATmega328 compatible - 4 analog channels at 10 bit resolution, 6 if RTC is not used
• Arduino Leonardo or ATmega32u4 compatible - 12 analog channels at 10 bit resolution
• Arduino Mega R3 or ATmega2560 compatible - 16 analog inputs (10-bit)
• Arduino Zero or ATSAMD21 compatible - 6 analog inputs (12-bit)
• Arduino Due - 12 analog inputs (12-bit)
