The Micro SD Storage Board for Arduino is a Micro SD card reader module and the SPI interface via the file system driver, microcontroller system to complete the Micro SD card read and write files. Users can directly use the Arduino IDE to come with an SD card to complete the library card initialization and read-write. 3.3V voltage regulator circuit: LDO regulator output is 3.3V level converter chip, Micro SD card supply. Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination,
