Micro SD Card Reader SPI Interface Module

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

Features

• supports Micro SD, Micro SDHC card (high card)
• onboard level conversion circuit that interfaces level can be either 5V or 3.3V
• power supply for 4.5V~5.5V, onboard 3.3V voltage regulator circuit
• the communication interface to the standard SPI interface
• 4 M2 screw holes for easy installation

Interface descriptions

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
