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. users can directly use the SD card library that comes with the 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;
Level shifting circuit: The signal to the direction of the Micro SD card is converted to 3.3V,and the MISO signal of the MicroSD card to the control interface is also converted to 3.3V.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.
