The Adafruit Data Logging Shield makes it easy to save sensor data to an SD card with accurate timestamps. It combines an SD card interface with a real-time clock (RTC) and a prototyping area on an Arduino-compatible shield, so you can be logging data within minutes of setup.

This R3-compatible version works with a wide range of Arduino boards. All components come pre-soldered and tested — you just need to solder on the headers to attach it to your Arduino.

Key Features

  • SD Card Interface – Supports FAT16 and FAT32 formatted cards with 3.3V level shifting to protect your SD card
  • Real-Time Clock (RTC) – Timestamps all data, battery backup lasts for years
  • On-Board 3.3V Regulator – Reliable reference voltage and stable SD card power
  • Prototyping Area – Solder space for connectors, sensors or additional circuitry
  • Library Support – Included libraries and example code for both SD and RTC

Compatibility

  • Arduino UNO / ATmega328 – 4 analogue channels at 10-bit (6 if RTC not used)
  • Arduino Leonardo / ATmega32u4 – 12 analogue channels at 10-bit
  • Arduino Mega R3 / ATmega2560 – 16 analogue inputs at 10-bit
  • Arduino Zero / ATSAMD21 – 6 analogue inputs at 12-bit
  • Arduino Due – 12 analogue inputs at 12-bit

Ideal For

  • Environmental and weather data logging
  • Sensor data recording for analysis
  • Long-term monitoring projects
  • Scientific experiments and field work

Package Contents

  • 1× Adafruit Data Logging Shield (assembled and tested, headers not installed)
Important: Arduino board, SD card and coin cell battery are not included. Headers need to be soldered on — basic soldering skills required.

The Adafruit Assembled Data Logging shield for Arduino appears in the following collections:
