Micro SD Card Mini TF Card Module

• Supports Micro-SD cards, Micro-SDHC card (high speed card)
• Micro-SD( less than equal 2G), Mirco SDHC( less than equal 32G)
• level conversion circuit board that interfaces level for 5V or 3.3V
• Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
• It is a standard communication interface SPI interface
• 4 M2 screw positioning holes for easy installation

Control Interface:

• A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is the power supply, MISO, MOSI, SCK is SPI bus, CS is the chip select signal pin; 3.3V voltage regulator circuit: LDO regulator output is 3.3V level converter chip, Micro-SD card supply;
• Level conversion circuit: Micro-SD card into the direction of the signal is converted to 3.3V, MicroSD card interfaces to control the direction of the MISO signal is also converted into 3.3V, general AVR microcontroller system can read the signal;Micro-SD card connector: a self-bomb deck, easy card insertion.
• the positioning of the module is easy to install, to achieve inter-module combination.
