Data logging Running out of memory space in your Arduino project? The SD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects.
The Shield can work with 5V or 3.3V power supply, and both 5V/3.3V IO operation level. It can be controlled directly by a wide range of microcontrollers.
It supports SD, SDHC, or MicroSD TF cards. It just uses the SPI ports of Arduino,and you can plug more other shield on it.There are flowerpad holes on the board for you DIY project.
