The features of the module are as follows:
-support Micro SD card, Micro SDHC card (high speed card)
-Onboard level shifting circuit, ie for 5V or 3.3V interface level
-power supply is 4.5V? 5.5V, 3.3V voltage regulator circuit, the communication interface is a standard SPI interface
5.4 M2 screw positioning hole for easy installation
Interface Description:
-Control interface: There are six pins (GND, VCC, MISO, MOSI, SCK, CS), GND is grounded, VCC is power supply, MISO, MOSI, SCK is SPI bus, CS is chip select signal pin;
2. 3.3V voltage regulator circuit: The output of the LDO regulator is a 3.3V level conversion chip, and the Micro SD card is supplied;
-Level-shifting circuit: Micro SD card to signal conversion 3.3V, the direction of the MicroSD card interface to control the direction of the MISO signal is also changed to 3.3V, the general AVR microcontroller system can read the signal;
Micro SD card connector: Self-elastic card holder for easy card insertion.
-Positioning hole: The diameter of the 4 M2 screw positioning hole is 2.2mm, so the module is easy to install and realize the module-to-module combination.
