Updated Tutorial: Micro SD Card Breakout Board Tutorial @ Adafruit Learning System

If you have a project with any audio, video, graphics, data logging, etc in it, you’ll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. There’s more flash (256K) but you can’t write to it as easily and you have to be careful if you want to store information in flash that you don’t overwrite the program itself!
