Description
The module (MicroSD Card Adapter) is a Micro SD card reader module, through the file system and the SPI interface driver, SCM system to complete the file read and write MicroSD card. Arduino users can directly use the Arduino IDE comes with an SD card library card to complete the initialization and read

Features
Support Micro SD Card, Micro SDHC card (high-speed card)
Onboard level conversion circuit, ie the interface level can be 5V or 3.3V
The power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit-board
The communication interface is a standard SPI interface
5.4 M2 positioning screw holes for easy installation

parameters
Power supply voltage VCC: 4.5 – 5.5
Electric current: 0.2 – 200 mA
Interface level: 3.3 or 5 V
Support Card Type: Micro SD card (<= 2G), Mirco SDHC cards (<= 32G)
Size: 42X24X12 mm
Weight: 5g

Control Interface:A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC for the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin;

3.3V voltage regulator circuit :LDO regulator for 3.3V output level converter chip, Micro SD card supply;

Level conversion circuit : Micro SD card to signal direction to convert 3.3V, MicroSD card interface to control the direction of the MISO signals are converted to 3.3V, general AVR microcontroller systems can read the signal;

Positioning holes : 4 M2 screw positioning holes with a diameter of 2.2mm, so that the positioning module is easy to install, to achieve inter-module combination;
