Micro SD card Tutorial How to add lots o’ storage with microSD (and SD) cards. 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 cant 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!

Awesome! I have this breakout board and plan to use it in my PipBoy project planned for later this year – I love the wiring diagrams and library examples in your tutorials!!
Cheers,
Kris

I have a question: Adafruit has two SD card shields for the Arduino; the data logger and the GPS logger one. Are they identical, except for the GPS chip socket? Could I use the GPS logger one even if I only use it for normal data logging?
