6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is the ground, VCC is the power supply, MISO, MOSI, SCK are the SPI bus, and CS is the chip select signal pin; 3.3V Regulator circuit： The 3.3V output by the LDO voltage regulator supplies power for the level conversion chip and Micro SD card; Level conversion circuit: Signals to the Micro SD card converts into 3.3V, and MISO signal from Micro SD card to control ports also is changed into 3.3V. Typically, the AVR microcontroller system can read this signal.

If it is the first time to use this board, the driver can be found under the Drivers of the Arduino IDE. 4. You can use the program of Arduino IDE, go to ..\Arduino-1.0\libraries\SD. Reboost Arduino IDE，click Open to open the CardInfo example, as shown below; Signal pins should be changed into pins which are connected to the module. In this experiment, D5 is the connected pin.
