To wire and use the Joy-IT COM-MSD Micro-SD Breakout Board with an Arduino, follow these steps:
1. Wiring:
- Connect the VCCa pin of the Micro-SD module to the 3.3V pin of the Arduino.
- Connect the GND pin of the Micro-SD module to the GND pin of the Arduino.
- Connect the CS pin of the Micro-SD module to any digital pin of the Arduino (e.g., A1).
- Connect the MOSI pin of the Micro-SD module to the MOSI pin of the Arduino (e.g., A2).
- Connect the CLK pin of the Micro-SD module to the CLK pin of the Arduino (e.g., A3).
- Connect the MISO pin of the Micro-SD module to the MISO pin of the Arduino (e.g., A4).
2. Library installation:
- Open the Arduino IDE and go to Sketch -> Include Library -> Manage Libraries.
- In the Library Manager, search for "SD" and install the SD library by Arduino, Spark Fun.
3. Code example:
- Open the example code by going to File -> Examples -> SD -> ReadWrite.
- Alternatively, you can use the provided code in the user guide.
- Upload the code to your Arduino.
4. Usage:
- The code example initializes the SD card, writes some data to a file named "test.txt", and then reads and prints the contents of the file.
- You can modify the code to suit your specific needs, such as changing the file name or the data being written.
Note: Make sure to use a logic level converter between the Arduino and the Micro-SD module, as the module operates at a 3V logic level.
