Micro SD Card Adapter DocumentationOverviewThe Micro SD Card Adapter is a small printed circuit board (PCB) designed to facilitate the connection of a micro SD card to a microcontroller or a single-board computer. It provides a convenient and compact way to add external storage to IoT projects, enabling the storage and retrieval of data, firmware updates, and more.PinoutThe Micro SD Card Adapter typically features the following pinout:| Pin | Function |
| --- | --- |
| VCC | Power supply (3.3V or 5V) |
| GND | Ground |
| CLK | Clock signal |
| CMD | Command signal |
| DAT0 | Data line 0 |
| DAT1 | Data line 1 |
| DAT2 | Data line 2 |
| DAT3 | Data line 3 |Code Examples### Example 1: Using the Micro SD Card Adapter with ArduinoThis example demonstrates how to use the Micro SD Card Adapter with an Arduino board to read and write data to a micro SD card.Hardware RequirementsArduino Board (e.g., Arduino Uno or Arduino Mega)
Micro SD Card Adapter
Micro SD card (up to 32GB)Software RequirementsArduino IDE (version 1.8 or later)Code
```c++
#include <SD.h>// Pin definitions
const int CS_PIN = 5; // Chip Select pin for the SD cardvoid setup() {
Serial.begin(9600);
pinMode(CS_PIN, OUTPUT);// Initialize the SD card
if (!SD.begin(CS_PIN)) {
Serial.println("Initialization failed!");
while (1);
}
Serial.println("SD card initialized successfully!");
}void loop() {
// Write data to the SD card
File dataFile = SD.open("data.txt", FILE_WRITE);
if (dataFile) {
dataFile.println("Hello, world!");
dataFile.close();
Serial.println("Data written to SD card.");
} else {
Serial.println("Error writing to SD card.");
}// Read data from the SD card
File readFile = SD.open("data.txt", FILE_READ);
if (readFile) {
while (readFile.available()) {
Serial.write(readFile.read());
}
readFile.close();
Serial.println("Data read from SD card.");
} else {
Serial.println("Error reading from SD card.");
}delay(1000);
}
```
### Example 2: Using the Micro SD Card Adapter with Raspberry Pi (Python)This example demonstrates how to use the Micro SD Card Adapter with a Raspberry Pi single-board computer to read and write data to a micro SD card using Python.Hardware RequirementsRaspberry Pi single-board computer (e.g., Raspberry Pi 3 or Raspberry Pi 4)
Micro SD Card Adapter
Micro SD card (up to 32GB)Software RequirementsRaspbian OS (version 10 or later)
Python 3.xCode
```python
import os# Mount the SD card
os.system("sudo mount /dev/mmcblk0p1 /mnt")# Write data to the SD card
with open("/mnt/data.txt", "w") as f:
f.write("Hello, world!
")print("Data written to SD card.")# Read data from the SD card
with open("/mnt/data.txt", "r") as f:
print(f.read())print("Data read from SD card.")# Unmount the SD card
os.system("sudo umount /mnt")
```
Note: Make sure to replace `/dev/mmcblk0p1` with the correct device path for your micro SD card.These examples demonstrate the basic usage of the Micro SD Card Adapter in different contexts. You can adapt and modify the code to suit your specific IoT project requirements.
