Pin Connections

Standard wiring:

  • CS: Pin 4 (default)
  • MOSI: Pin 11
  • MISO: Pin 12
  • SCK: Pin 13
  • VCC: 5V power
  • GND: Ground
Use software SPI for custom pins
Use level shifter for 5V boards
Level shift for 5V microcontrollers

Software Setup

Arduino SD library provides simple functions for file operations. Standard commands include begin, open, write, read, and close. The library supports multiple files and directory structures.

Simple Commands - Easy file operations

Multiple Files - Supports directory structure

Works with Arduino IDE examples
Compatible with most libraries

√ Pre-tested for reliability

√ Standard SPI interface

√ Card detection included

Usage Tips

Common operations include creating text log files, storing configuration data, playing WAV audio files, and displaying BMP images. Format card as FAT32 first for best compatibility.

Format card as FAT32 first
Use card holder for easy swapping
Do not remove card during write
Use proper shutdown sequence

Troubleshooting

Card not detected:

  • Check SPI connections
  • Verify card format
  • Avoid unsupported card types

Read/write errors:

  • Check power supply
  • Use quality SD cards
  • Avoid corrupt file systems
