Description
Micro SD Card Reader Module also called Micro SD Adaptor is designed for dual I/O voltages. This Module is a simple solution for transferring data to and from a standard SD card. The pinout is directly compatible with Arduino, but can also be used with other microcontrollers. This module has SPI interface which is compatible with any sd card and it use 5V or 3.3V power supply which is compatible with Arduino UNO/Mega.SD module has various applications such as data logger, audio, video, graphics.
Support Micro SD Card, Micro SDHC card (high-speed card)
The level conversion circuit board that can interface level is 5V or 3.3V
Communication interface is a standard SPI interface
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 the SPI bus, CS is the chip select signal pin;
3.3V regulator circuit: LDO regulator output 3.3V as level converter chip, Micro SD card supply;
Level conversion circuit: Micro SD card into the direction of signals into 3.3V, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal;
Micro SD card connector: yes since the bomb deck for easy card insertion and removal.
Positioning holes: 4 M2 screws positioning hole diameter of 2.2mm, easy to install positioning, to achieve inter-module combination;
