What it does: 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. Built-in level adjustment: The module built-in level regulator circuit, level conversion circuit board that can interface level is 5V or 3.3V. Specifications: Voltage: 4.5V~5.5V DC;Communication Interface: Standard SPI;Interface Voltage Level: 3.3V or 5V;Applicable card type: Micro SD Card, Micro SDHC Card. Easy to read signal: Micro SD card to signal the direction of converts 3.3V, Micro SD card interface to control the direction of the MISO signal is also converted to 3.3V, general AVR microcontroller systems can read the signal. Standard interface: 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.
