This SD Card module makes it easy to add an SD Card reader/writer to your application. It makes all the SD Card signals available via a standard 2.54mm pin header. Through programming, you can read and write to the SD card using your nearly any microcontroller, like Arduino, PIC, AVR and others. This board has an onboard 3.3V regulator, meaning it can be used with 5V and 3.3V projects.
