The module (MicroSD Card Adapter) is aMicro SD card reader module, and the SPI interface via the file system driver,microcontroller system to complete theMicroSD card read and write files.users can directly use the IDE comes with an SD card to complete thelibrary card initialization and read-write Module features are as follows: 1 Support Micro SD Card, Micro SDHC card(high-speed card) 2 the level conversion circuit board that caninterface level is 5V or 3.3V 3 power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board 4. Communication interface is a standard SPI interface 5. 4 M2 screw positioning holes for easy installation Control Interface: A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND toground, 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 output3.3V as level converter chip, Micro SDcard supply; Level conversion circuit: Micro SD card intothe direction of signals into 3.3V, MicroSDcard toward the direction of the control interface MISO signal is alsoconverted to3.3V, general AVR microcontroller system can read the signal; Micro SD card connector: yes since the bombdeck for easy card insertion and removal. Positioning holes: 4 M2 screws positioning hole diameter of 2.2mm, the module is easy to install positioning, to achieve inter-modulecombination;
