Arduino is a popular platform for DIY electronics projects. Arduino models vary, but the Due and Mega are two of the more commonly used. So, which one should you choose for your project? In this blog post, we will compare the Arduino Due and Mega to help you decide which one is right for you.
What Is Arduino Due?
The Arduino Due is the first board from Arduino that uses a 32-bit ARM core processor. This product has 54 digital input/output pins, 12 analog inputs, 4 UARTs, a 84 MHz clock, an USB OTG capable connection, 2 DACs , 2 TWIs , a power jack, an SPI header), and a reset button.
It is designed to be compatible with most shields designed for the Uno R3. The Arduino Due can be powered via the USB connection or from an external power source. The power source is selected automatically. 
What Is Arduino Mega?
This product has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
The Arduino Mega 2560 is a replacement for the earlier Arduino Mega, which was based on the ATmega1280. The Arduino team decided on the ATmega2560 because it provided more memory space and could handle processing power better than the earlier board. 
Differences between Arduino Due and Arduino Mega
Use of Processor
The Atmel SAM3X8E processor powers both the Arduino Due and Mega. This is an ARM Cortex-M3 microcontroller. The primary distinction between the two boards is that the Mega has an older model of processor. The Arduino Due uses the Atmel SAM3X8E, which is a 32-bit microcontroller. The SAM3X8E has a maximum clock speed of 96 MHz and can be overclocked to 120 MHz.
Total Voltage Supply for Board
The Arduino Due and the Arduino Mega can both be powered from an external source or USB. The power source can be anything from an AC-to-DC adapter to a battery. The Arduino Mega can be powered with an external power supply of up to 12 volts.
Digital I/O Pins
Arduino Due has more digital input/output pins (54) than Arduino Mega (50), and 12 of those can be used as PWM outputs. This difference is due to the fact that the SAM3X8E processor in the Due has more GPIO pins than the ATmega2560 processor in the Mega.
Analog Input Pins
The Arduino Due has twelve analog input pins, whereas the Mega has sixteen.
Arduino Due has 4 UARTs while Arduino Mega has only 1 UART. The SAM3X8E processor in the Due has more UARTs than the ATmega2560 processor in the Mega.
Size of Flesh Memory
While Arduino Mega only has 128 KB of flash memory, Arduino Due boasts 256 KB. The SAM3X8E processor in the Due has more flash memory than the ATmega2560 processor in the Mega, accounting for this difference. 
Arduino Due’s speed is 96 MHz while Arduino Mega maxes out at 8 MHz. This difference is due to the fact that the SAM3X8E processor in the Due is a 32-bit processor while the ATmega2560 processor in the Mega is only an 8-bit processor.
The Arduino Due has double the micro USB ports that the Arduino Mega does.
The Arduino Due is slightly more costly than the Arduino Mega.
Arduino Due is bigger than Arduino Mega.
Arduino Due is not able to be used with Arduino Mega shields. 
Suitable Projects for the Arduino Due vs. Mega
When it comes to choosing between the Arduino Due and the Arduino Mega, it really depends on what kind of project you’re working on. If you need more digital I/O pins, then the Mega is the better choice. If you need more processing power and memory, then the Due is the better board.
Projects that would work better with an Arduino Mega include:
- A data logging project that requires a lot of digital input/output pins
- A project that uses multiple servo motors
- A project that needs to store a lot of data
And here are some examples of projects that would be better suited for the Arduino Due:
- A project that requires a lot of processing power (e.g. image processing)
- A project that uses a lot of sensors
- A project that needs to send and/or receive data over USB or Ethernet
So, which board should you choose for your project? It really depends on your specific needs. If you’re not sure, then it’s probably best to start with the Mega since it has more flexibility.
Pros and Cons of Arduino Due vs. Mega
With the knowledge of how the Arduino Due and Mega differ, we can take an in-depth look at their pros and cons.
Arduino Due Pros:
- More processing power and memory than the Mega
- Can communicate with other devices over USB or Ethernet
- Native support for 3.3V devices
Arduino Due Cons:
- More expensive than the Mega
- Fewer digital I/O pins
Arduino Mega Pros:
- More affordable than the Due
- More digital I/O pins than the Due
- Can be used with existing Arduino shields
Arduino Mega Cons:
- Less processing power and memory than the Due
- No Ethernet or USB support (requires external shield)
So, there you have it! Now you are informed of the distinctions between the Arduino Due and the Arduino Mega. Depending on your project requirements, one of these boards may be a better fit than the other. So, choose wisely!
Alternatives to Arduino Due and Mega
When it comes to choosing an Arduino board for your project, the options can feel overwhelming. In addition to the Due and Mega, there are a number of other boards available on the market. Here’s a quick rundown of some of the most popular alternatives:
It’s relatively inexpensive and features a wide range of capabilities, making it perfect for learning the basics of Arduino programming. 
Arduino Nano – The Nano is a smaller, more compact version of the Uno. It’s perfect for projects that require a smaller footprint, such as wearable electronics or robotics.
Arduino Pro Mini – The Pro Mini is even smaller than the Nano and is designed for applications where space is at a premium. It’s also one of the lowest-cost Arduino boards available.
Arduino Mega 2560 – The Mega 2560 is the largest and most powerful Arduino board. It’s ideal for projects that require a lot of processing power, such as video or audio applications.
So, which board is right for your project? That depends on a number of factors, including cost, size, and capabilities. If you’re just starting out with Arduino, the Uno is probably your best bet. If you need a board with more capabilities, the Mega 2560 is a good option. And if space is limited, either the Nano or Pro Mini would be a good choice.
No matter which board you choose, you’re sure to find that Arduino is a great platform for learning, experimenting, and creating. So have fun and let your imagination run wild!
How Does an SBC Work?
SBCs are often used in embedded systems, which are systems that consist of software and hardware components that interact with each other to perform a specific task.

Microcontrollers are designed for projects that require a low-power, low-cost solution. They’re typically used in applications where space is limited, such as in wearable devices or automotive electronics. Microcontrollers typically have less processing power than an SBC, but they make up for this by being more energy-efficient.
SBCs are designed for projects that require more processing power than a microcontroller can provide. They’re often used in applications where there’s a need for multitasking or multimedia support, such as in industrial automation or gaming systems. SBCs typically cost more than microcontrollers, but they offer more features and performance.
So, which one is right for your project? If you need a low-power solution with limited processing power, then a microcontroller is a good choice. If you need more processing power and features, then an SBC is the way to go.
Things to Consider When Using SBCs
There are a few things you should consider when using SBCs:
