Feel like you don’t know enough about Arduino? Yes, we understand. The world of microcontrollers and programmable circuits complexifies quickly. Don’t be afraid! Beginners interested in IoT and electronics projects often use the Arduino Due, and we’ll explain how to get started. This page will explain the Due’s features, which projects it’s perfect for, and where to learn more. Stay with us and you’ll construct and program circuits and gadgets quickly!

Introducing the Arduino Due

The Arduino Due uses the Atmel SAM3X8E ARM Cortex-M3 CPU.

Speed and Power

The Due has more processing power and speed than the Uno and Mega. Its 32-bit ARM CPU can reach 96 MHz, compared to the Uno’s 16 MHz 8-bit processor. The Due can handle more sophisticated programs and mathematical functions due to its speed and bit depth.

More Memory

Besides a faster processor, the Due features larger memory. Its 512 KB flash memory stores programs and its 96 KB RAM stores variables and runs programs. The Due can run more complex programs than the Uno due to its greater memory.


The Due is more powerful but compatible with numerous Arduino shields and libraries. A few shields may need slight tweaks, but most will work with the Due. Much of the Arduino core software works on the Due, however certain functions have been upgraded for 32-bit architecture.


The because is ideal for complicated applications that require faster processing or more memory because to its power. Projects suitable for the Due include:

  1. High-resolution camera computer vision applications
  2. Advanced, sensor- and motor-rich robots
  3. Interactive installations with many inputs/outputs
  4. Advanced data analysis and logging

The Due’s speed, memory, and Arduino compatibility enable complex electronics applications on the Arduino platform. The Due, however more complicated than an Arduino, is a good next step for makers eager to develop their abilities and ideas.

Key Features and Specifications of the Arduinos Due

The Arduinos Due uses the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board with a 32-bit ARM core CPU, the Atmel SAM3X8E. It is the Arduino Uno’s successor with 54 digital input/output pins and 12 analog inputs.

Powerful Processor

The Due’s 32-bit ARM core microcontroller is a big improvement over other Arduino boards’ 8-bit ones. It can tackle more difficult computing jobs due to its higher processing power. The 84 MHz clock speed is quicker than the Uno’s 16 MHz.

More Memory

Compared to the Uno, the Due has 8 times more flash memory and 16 times more RAM with 512 KB and 96 KB, respectively. This extra RAM lets you execute more advanced board programs.

Faster Communication

The Due has native USB communication, unlike the Uno, which needs an FTDI chip. It transfers data quicker over USB at 480 Mbps. The board supports CAN 2.0B at 1 Mbps with two CAN bus connections.

Rich Peripheral Set

Due has 54 digital I/O pins and 12 analog inputs, giving you various peripheral connection choices. It supports I2C, SPI, and UART. Pins can provide pulse-width modulated signals for LED dimming and motor speed control.

In conclusion, the Arduinos Due expands 8-bit Arduino capabilities. The Due is ideal for projects that need extra processor, memory, or I/O. Though more complicated, it outperforms the Uno and Mega. The Arduino Due is great for robotics, automation, and complex electronics.

Setting Up the Arduino Due

Arduinos Due requires installing the Arduino Software (IDE) and connecting the board. Write and upload programs to your Arduino board with the Arduino IDE.

Installing the Arduino IDE

Download the newest Arduino IDE from the Arduino website. Install it on your computer. Support the Arduino Due board next. File > Preferences in Arduino IDE. Use “” as an Additional Board Manager URL. Install Arduino SAM Boards under Tools > Boards Manager.

Arduino Due connection

The Arduinos Due connects to your computer via micro USB. Plug the USB cord into the Arduino Due’s Programming port and your computer’s USB port.

Choice of Arduino Due board

Go to Tools > Board in the Arduino IDE and select “Arduino Due (Programming Port)”. This lets you upload code to the Arduinos Due’s primary microcontroller.

Write Your First Program

Upload a simple LED-blinking test application to check setup. Put an LED on pin 13 and ground. Open File > Examples > 01.Basics > Blink in Arduino IDE. Compile and upload the code to Arduino Due by clicking Upload. The Arduinos Due’s pin 13 LED will glow if the upload is successful!

Arduino Due Programming
Install Arduino IDE

Arduino Due programming requires the Arduino IDE on your computer. This free software lets you upload C/C++ code to Arduino. Download and install the newest IDE on your PC or Mac.

Choosing Arduino Due Board

Select the Arduinos Due board after installing the IDE. In the IDE, select “Arduino Due (Programming port)” under Tools > Board. This instructs the IDE to program an Arduino Due.

Connect Arduinos Due

Plug your Arduinos Due into your computer via USB. The Due is powered and programmed via its USB connector.

Write Your First Program

Write a basic LED blinking application. In IDE, select File > New. Start a new drawing. Enter this code:

function setup() { pinMode(13, OUTPUT);

void loop() { digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); }

Pin 13 is the output, and this code blinks the LED on and off for one second and repeats.

Upload Program

Click “Upload” in the upper left of the IDE to upload the application to Arduino Due. Code will be compiled and published to the board. Pin 13’s LED blinks after a few seconds!

Congratulations on programming your first Arduino Due sketch! You may now develop more sophisticated projects with this powerful board. With its quick clock, big memory, and many I/O pins, the Due offers many options. Enjoy your experiments!
