Hailege Stackable SD Card and TF Card Shield SD Card Shield for Arduino UNO R3

Features: Compatible SD card, Micro SD card and SDHC card supportable.Prototype expand Library support Size: 53mm x 47mm Pin With SD Card 5V VCC---3.3V GND--GND D13---SD_CLK D12-- SD_OUT D11---SD_IN D10--SD_CS If you need those two for I2C communication like a display shield, you have to use Analog pin 4 and Analog pin. Put the SD shield on whatever arduino you have. Using the labels on the shield and arduino, make sure the pins match. Use the wiki instructions' "Compatibility" section to find out what position the 3.3V/5V selector switch should be in, and whether you need to remove ALL 3 of the adjacent SPI Jumpers on the top of the board given the arduino board you're using. For the arduino DUE,you can remove these jumpers and keep the switch on 3.3V. Package included: 1* Stackable SD Card and TF Card Shield for Arduino UNO R3
