What it does

The SD Card Module enables microcontrollers to read and write data to standard SD cards via SPI interface. It is essential for data logging, audio storage, file systems, and expandable non-volatile memory in embedded projects.

Key features

  • SD card interface via SPI
  • Standard SD and microSD (with adapter)
  • 3.3V-5V compatible (with level shifter)
  • FAT16/FAT32 support
  • High capacity storage
  • Low cost per MB
  • Hot-swappable (with care)

Good to know

  • Use SD library (built into Arduino IDE)
  • Format card as FAT16 or FAT32
  • Use quality SD card for reliability
  • CS pin must be configured correctly
  • Some cards incompatible – test with known good card
  • Properly close files before power-off to avoid corruption
