: Support Micro SD card, micro SDHC card Interface level: 5V Powr supply: 5V , 5V voltage regulator circuit board Currency: 0.2-200mA Size:4.00*2.00*1.00 (About 1.3inch X 0.8inch X 0.4inch) Communication interface: SPI With 4 holes for M2 screw , it is easy to install 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. Arduino users can directly use the SD card library that comes with the Arduino 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 regulator circuit: 5V of LDO regulated output is level conversion chip, Micro SD card power supply; Level shifting circuit: The signal to the direction of the Micro SD card is converted to 5V, and the MISO signal of the MicroSD card to the control interface is also converted to 5V. 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.
