Update: After taking a figurative lashing from the comments section we're begging for mercy by updating the microSD Shield board. All new microSD shields have a voltage converter chip on-board that converts the Arduino 5V signals to 3.3V signals in accordance with SD specifications. No more 'blown up' SD cards!
Running out of memory space in your Arduino project? The microSD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects.
Communication with microSD cards is achieved over an SPI interface. The SCK, DI, and DO pins of the microSD socket are broken out to the ATmega168/328's standard SPI pins (digital 11-13), while the CS pin is broken out to Arduino's D8 pin. The shield also includes a large prototyping area with a 13x12 grid of 0.1" pitch PTHs.
This shield comes populated with a microSD socket, red power indicator LED, and a reset button; but it does not come with headers installed. We recommend the 6 and 8-pin stackable headers.
