SD Card Reading and Writing Module SPI Interface

Product description:

1. The module (SD Card Adapter) is an SD card reader module and the SPI interface via the file system driver, microcontroller system to complete the SD card read and write files
2. Users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read-write
3. 3.3V voltage regulator circuit: LDO regulator output is 3.3V level converter chip, SD card supply
4. SD card connector: a self: bomb deck, easy card insertion
5. Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination
6. Please note it is an SD cardholder not "microSD"(the one commonly used in mobile phones), however, you can use a microSD card with this module with a size converter adapter board

Features:

1. The level conversion circuit board that can interface level is 5V or 3.3V support SD card, SDHC card (high-speed card) Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
2. Communication interface is a standard SPI interface
3. The communication interface is a standard SPI interface; 4 M2 screw positioning holes for easy installation
4. 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
5. Level Conversion Circuit: SD card into the direction of signals into 3.3V, SD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal
6. 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
