SD Memory Card Breakout Board
Easily add rewritable storage to your Arduino or other development board with this SD card breakout board from PMD Way.
This board not only includes the card socket, but also the level converter so it's both 3.3V and 5V tolerant - ideal for Arduino Uno, Mega, Due and all the others. The mounting holes are M2 2.2mm diameter.
You can use SD cards up to 2GB or SDHC cards up to 32GB in size.
The interface is the standard SPI bus and all the pins are labelled neatly as shown in the product images. We also have full-sized SD card breakout boards and an Arduino shield.
