• Wide Range of I/O Pins: Includes multiple digital and analog input/output pins for versatile project options.

• User-Friendly Development: Supported by the Arduino IDE, with plenty of libraries and examples for easy prototyping.

• IoT Capabilities: Enables Internet of Things (IoT) projects with cloud integration, remote device control, and data collection.

• Cross-Platform Compatibility: Works with Windows, Mac, and Linux operating systems.

• Open-Source Support: Active community support, tutorials, and forums for easy learning and troubleshooting.

• Versatile Applications: Suitable for home automation, robotics, IoT devices, environmental monitoring, and more.

Principle of Work:

• Microcontroller: Uses the ATmega4809 microcontroller for code execution and control.

• WiFi Communication: Supports protocols like TCP/IP, HTTP, and MQTT for wireless data transmission.

• I/O Pins: The board has digital, analog, PWM, SPI, I2C, and UART pins for various devices and sensors.

• Power Supply: Powered via USB or an external 7-12V DC supply.

Applications:

• Home Automation: Remotely control and monitor appliances and systems.

• IoT Projects: Build connected devices that interact with the internet or cloud platforms.

• Environmental Monitoring: Collect data from sensors and send it online for analysis.

• Robotics: Control robotic systems with remote access.

• Weather Stations: Build systems to monitor and report weather conditions.

• Smart Agriculture: Automate irrigation systems, monitor crops, and environmental conditions.

Technical Details:

• Secure Element: ATECC608A

• Radio Module: u-blox NINA-W102

• Inertial Measurement Unit: LSM6DS3TR

• Microcontroller: ATmega4809

• Operating Voltage: 5V

• Pinout: Includes 14 digital pins, 6 analog pins, and multiple communication options (SPI, I2C, UART).

• Size: 53 x 68 mm, Weight: 25g

Libraries and Setup:

• Ensure the Arduino IDE is installed, select the correct board type, and set up the port for uploading code.

• Use a simple Blinking LED code to test the functionality.

Sample Code for LED Blink:

const int LED_PIN = 13;
const int BLINK_INTERVAL = 1000;

void setup() {
  pinMode(LED_PIN, OUTPUT);
  Serial.begin(9600);
  while (!Serial) { }
  Serial.println("Blinking LED with Serial Monitor Status");
}

void loop() {
  digitalWrite(LED_PIN, HIGH);
  Serial.println("LED ON");
  delay(BLINK_INTERVAL);
  
  digitalWrite(LED_PIN, LOW);
  Serial.println("LED OFF");
  delay(BLINK_INTERVAL);
}

Comparisons:

• WiFi Connectivity: The Arduino UNO WiFi Rev 2 has built-in WiFi, while the Arduino UNO Rev 3 requires external shields for WiFi.

• Power Supply: Both can be powered via USB or external power, but the WiFi Rev 2 can also be powered through Ethernet (PoE).
