Micro SD Card Reader Module - SPI interfaces with level converter chip (Arduino Compatible)

Features:

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

Module features are as follows:

• 1. Support MicroSD Card(<=2G), Micro For SDHC card (<=32G)(high-speed card)
• 2. The level conversion circuit board that can interface level is 5V or 3.3V
• 3. Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
• 4. Communication interface is a standard SPI interface
• 5. 4 M2 screw positioning holes for easy installation
• 6. Size: 4.1x 2.4cm

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, MicroSD card supply

Level conversion circuit:
MicroSD 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

MicroSD card connector:
Since the bomb deck for easy card insertion and removal.

Positioning holes:
4 M2 screws positioning hole diameter of 2.2mm, the module is easy to install positioning, to achieve inter-module combination
