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.
The Micro SD card converts 3.3V to indicate direction, its interface for controlling MISO signal direction is also converted to 3.3V, allowing general AVR microcontroller systems to read the signal.
The module built-in level regulator circuit, level conversion circuit board that can interface level is 5V or 3.3V.
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.
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.
