The Adafruit Data Logging shield is back once again! This new revision is compatible with just about all Arduino R3 compliant boards. The data logging shield allows your Arduino to log time stamped data with relative ease. The board is quick to set up and should be running and saving data in less than 15 minutes for anyone familiar with the Arduino platform.

The shield has an SD card slot (which can be used with a microSD card and SD adapter), a built in RTC (real time clock) with battery backup, and a small prototyping area for any additional circuitry you need to add. Just solder in the included breakaway headers and you are ready to go!

This new version is compatible 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)

Of course you can log anything you like, including digital sensors that have Arduino libraries, serial data, bit timings, and more!

This breakout uses a CR1220 battery. Due to shipping regulations, a battery is not included



  • Compatible with a wide variety of Arduino and Arduino compatible boards
  • Works with FAT16 or FAT32 formatted cards
  • SD Card protrudes by 10mm (0.4in) when inserted
  • Real time clock (RTC) keeps the time going even when the Arduino is unplugged
  • 3.3v level shifter circuitry prevents damage to your SD card
  • The RTC uses I2C 7-bit address 0x68.
