SD Card Module
The SD Card Module is a popular component used to add mass storage capabilities to microcontroller-based projects, such as those built with Arduino. It allows users to read from and write to SD cards (Secure Digital cards), making it ideal for storing data like logs, configurations, or multimedia files in embedded systems. The SD Card Module typically uses the SPI (Serial Peripheral Interface) communication protocol to interact with the microcontroller.
By interfacing with the Arduino, the SD card module enables projects to store and retrieve large amounts of data without the need for external computers. This is particularly useful for applications such as data logging (temperature, humidity, or sensor data), storing text or CSV files, or playing audio files in media players. The module can support a variety of SD cards, ranging from 2GB to 32GB or even larger, depending on the card type (SD, SDHC, etc.).
Using libraries like SD.h in Arduino, users can easily implement functions to create, read, write, and delete files on the SD card. The module typically includes a level shifter to ensure that the voltage levels are compatible with 3.3V or 5V microcontrollers. It’s widely used in data-intensive applications, such as weather stations, audio playback systems, and even simple file storage systems, offering a straightforward solution for adding external storage to any project.
