Features

  • Designed specifically for Arduino Mega boards
  • Integrated Micro SD card reader and writer
  • Supports FAT16 and FAT32 formatted SD cards
  • Extra soldering area for custom prototyping
  • Easy connection of sensors, relays, servos, and other modules
  • Flexible chip select and card detect pin configuration
  • Supports external power or Arduino 5V power supply

 

Micro SD Card Function

The onboard SD card interface allows reading and writing data to standard Micro SD cards. The card must be formatted using FAT16 or FAT32 file systems. The chip select and card detect pins can be connected to any available Arduino Mega input or output pin using jumper wires.

Pinout Overview

  • 5V Arduino 5V power supply
  • GND Common ground
  • Digital pins Available through shield headers
  • Analog pins Available through shield headers
  • CS SD card chip select configurable via jumper wire
  • CD SD card detect configurable via jumper wire

Applications

  • Data logging projects
  • Sensor monitoring systems
  • Robotics control platforms
  • Educational Arduino experiments
  • Rapid prototyping and testing

 

Arduino Test Code

#include <SPI.h>
#include <SD.h>

const int chipSelect = 4;

void setup() {
  Serial.begin(9600);

  if (!SD.begin(chipSelect)) {
    Serial.println("SD card initialization failed");
    return;
  }

  Serial.println("SD card ready");

  File dataFile = SD.open("datalog.txt", FILE_WRITE);

  if (dataFile) {
    dataFile.println("Sensor Shield Data Logger Test");
    dataFile.println("Logging successful");
    dataFile.close();
    Serial.println("Data written to SD card");
  } else {
    Serial.println("Error opening datalog.txt");
  }
}

void loop() {
}
