SD Card Module
SD Card Module
The module (MicroSD Card Adapter) is a Micro SD card reader module and the SPI interface via the file system driver, and microcontroller system to complete the Micro SD card read and write files. Users can directly use the Arduino IDE that comes with an SD card to complete the library card initialization and read-write. 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, and a general AVR microcontroller system can read the signal , . Micro SD card connector: a self: bomb deck, easy card insertion. 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.
Applications:
- Data loggers Audio
- Video storage
- Visualization Expandable memory

1. What is an SD card do?
- The SD card modules allow you to communicate with the memory card and write or read the information on them. The module interfaces with the SPI protocol. To use these modules with Arduino you need the SD library. This library is pre-installed on the Arduino application.
2. What is the SD Card module?
- A Secure Digital (SD) card is a tiny flash memory card designed for high-capacity memory and various portable devices, such as car navigation systems, cellular phones, e-books, PDAs, smartphones, digital cameras, music players, digital video camcorders, and personal computers.
3. How do I use an SD card module with an Arduino?
- VCC pin supplies power for the module and should be connected to 5V pin on the Arduino.
- GND should be connected to the ground of Arduino.
- MISO (Master In Slave Out) is SPI output from the Micro SD Card Module.
- MOSI (Master Out Slave In) is SPI input to the Micro SD Card Module.
- SCK (Serial Clock) pin accepts clock pulses that synchronize data transmission generated by Arduino.
- SS (Slave Select) pin is used by Arduino(Master) to enable and disable specific devices on the SPI bus.
