The module (microsd card adapter) is a micro sd card reader module, and the spi interface via the file system driver, micro controller system to complete the micro sd card read and write files. Users can directly use the Ar-duino ide comes with an sd card to complete the library card initialization and read-write. Support micro sd card, micro sdhc card (high-speed card) the level conversion circuit board that can interface level is 5v or 3. 3vpower supply is 4. 5v ~ 5. 5v, 3. 3v voltage regulator circuit board communication interface is a standard spi interface 4 m2 screw positioning holes for easy installation control interface: A total of six pins (gnd, vcc, miso, mosi, sck, cs), gnd to ground, vcc is the power supply, miso, mosi, sck is the spi bus, cs is the chip select signal pin 3. 3v regulator circuit: Ldo regulator output 3. 3v as level converter chip, micro sd card supply level conversion circuit.
