Description:
This module (MicroSD Card Adapter) is a Micro SD card read/write module via the file system driver and SPI interface, SCM system to complete read or write a file in the MicroSD card. Arduino users can directly use the Arduino IDE comes with SD card library card is done initializing and reading and writing
Module features are as follows:
1. supports Micro SD, Micro SDHC card (high card)
2. onboard level conversion circuit that interfaces level can be either 5V or 3.3V
3. power supply for 4.5V~5.5V, onboard 3.3V voltage regulator circuit
4. the communication interface to the standard SPI interface
5.4 M2 screw holes for easy installation

Interface description:
Control interface: All 6 pins (GND, and VCC, and MISO, and MOSI, SCK, and CS), GND, VCC power supply, MISO, MOSI, SCK-SPI bus, CS chip select signals feet;
3.3VVoltage regulator circuit: 3.3V LDO Voltage Regulator outputs to power level conversion chip, Micro SD card;
Level shifting circuit: Signals into 3.3V,MicroSD towards the Micro SD card card interface to control the direction of MISO signals are converted into 3.3V, AVR single-chip microcomputer system can read the signals;
Micro SDCard connector: Is the playing card holder, card swap.
Locating holes: 4 M2 screw locating hole aperture of 2.2mm, making positioning module is easy to install, module combination;
