The module (MicroSD Card Adapter) is a Micro SD card reading and writing module.
Through the file system and SPI interface driver, the MCU system can complete the reading and writing of files in the MicroSD card.
Compatible Ar-duino users can directly use the SD card library that comes with the Ar-duino IDE to initialize and read the card.

Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin.
5V voltage stabilizing circuit: The 5V output of the LDO voltage stabilization is the power supply for the level conversion chip and the Micro SD card.
Level conversion circuit: the signal to the Micro SD card is converted to 5V, and the MISO signal from the Micro SD card to the control interface is also converted to 5V, which can be read by the general AVR microcontroller system.
Generally, the AVR microcontroller system can read the signal.
Micro SD card holder: It is a self elastic card holder for easy insertion and removal of cards.
