Technical Specifications: Voltage: 4.5V~5.5V DC Current: 0.2~200mA Communication Interface: Standard SPI Interface Voltage Level: 3.3V or 5V Applicable card type: Micro SD Card(less than 2G), Micro SDHC Card(less than 32G) Control Interface: (GND, 3V3, MISO, MOSI, CLK, CS), GND to ground, 3V3 is the power supply, MISO, MOSI, CLK for SPI bus, CS is the chip select signal pin Micro SD card connector: Self bomb deck, easy card insertion Package includes: 12 x Micro SD Card Adapter

The communication interface is a standard SPI interface, easy to connect to any device with SPI interface; 2 M2 screws positioning holes with a diameter of 2.2mm, so the module is easy to install positioning, to achieve inter-module combination. The module (Micro SD Card Adapter) is a Micro SD card reader module, through the file system and the SPI interface driver, SCM system to complete the file to read and write MicroSD card. Arduino users can directly use the Arduino IDE comes with an SD Card to complete the library card initialization and read-write.
