Description of product


The Micro SD 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 Arduino IDE comes with an SD card to complete the library card initialization and read-write.
