Micro SD Storage Board TF Card Module Slot Socket Memory Shield Module SPI for Arduino Micro SD Card Reader Module

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 to read and write MicroSD card. Arduino users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read.

Module features are as follows:

1.It supports Micro SD card,Micro SDHC card
2.Board level conversion circuit, namely, interface level for 5 V or 3.3 V
3.Power supply:4.5V~5.5V,the onboard 3.3 V voltage regulator circuit
4.Communication interface is a standard SPI interface
5.4 M2 screw positioning hole, easy to install

Interface parameters:

Project Minimum Typical projects Maximum Unit

VCC 4.5 5 5.5 V

Current 0.2 80 200 mA

Interface level 3.3 or 5 V

Support Card Type Micro SD card (<= 2G), Mirco SDHC card (<= 32G)

Size 42X24X12 mm

Weight 5 g

Control interface

1.Six pins (GND, VCC, MISO, MOSI, SCK, CS) GND is grounding wire,VCC is power supply, MISO, MOSI, SCK are bus of SPI, CS for foot piece of selected signal.
2.The output voltage of 3.3 V for level conversion chip, Micro SD card
3.The Micro SD card direction of signal is converted into 3.3 V, MicroSD card to control interface of MISO signal is transformed into 3.3 V, general AVR single chip microcomputer system can read the signal;
4.Micro SD is the booth, persons possessing plug

Interface as shown Mirco SD card module is shown below:
