Overview

The DFR0229 is a compact Micro SD card expansion module designed for seamless integration with the Arduino platform. It provides a standard SPI interface to enable data logging and storage capabilities for embedded projects. The board is optimized for 5V operation, making it directly compatible with classic Arduino boards like the Uno and Mega.

Why Choose This Part

The module features a small 20mm x 28mm footprint, allowing it to be integrated into space-constrained enclosures. It simplifies hardware design by breakout of the SPI pins and providing a reliable 5V power interface for standard SD card operations.

Applications

Data Logging
Recording sensor readings such as temperature, humidity, or GPS coordinates to a Micro SD card for long-term analysis.
Configuration Storage
Storing persistent device settings or lookup tables that are too large for internal EEPROM.
Media Playback
Serving as a storage backend for audio files or low-resolution bitmap images in human-machine interface projects.

Getting Started

Connect the module to your Arduino via the SPI bus (MOSI, MISO, SCK, and a digital pin for Chip Select). Use the standard Arduino SD library to initialize the card and perform file read/write operations. Ensure your card is formatted to FAT16 or FAT32 before use.

Also Consider

Adafruit MicroSD Card Breakout Board Adafruit - Includes an onboard level shifter and 3.3V regulator for compatibility with both 3V and 5V logic.
