Arduino Mega and Arduino Due – A Quick Discussion
Arduino Due, also known as Arduino Duemilanove, is a prototyping board offered by Arduino, which has 54 GPIO pins, just like the Arduino Mega. The microcontroller unit in the Arduino Due is more powerful and efficient than the Mega 2560. The significant difference between the Arduino Mega and Due is that the latter can only operate and supply voltages of 3.3 volts and external level. Level shifters must be used to get a voltage of 5 volts range.
Features of Arduino Due
The microcontroller unit present on the board brings out the difference in the Arduino Mega and Due. It makes the operating voltage in the Arduino Mega and Due different. The microcontroller AT91SAM3X8 in Arduino Due is an ARM Cortex-M0 MCU, which is unlike the AVR MCU, which is used in Arduino Mega. The Arduino Nano and Uno offer very high performance compared to AVR MCU.
The number of GPIO pins in Arduino Due remains almost similar to that of the Mega, and there are 12 PWM pins to operate. Different appliances like servo motors, which is again appreciable, each GPIO pin present on the Arduino Due, has very high power lines and can tolerate a current flow of up to 800 milliamps, which means that each can operate a six phase stepper motor directly without any driver modules, this is definitely to be noted and an appreciable feature.
Power Supply
The Arduino Due is powered by an external power supply of 7 to 12 volts, and it can also be powered by a Li-Po battery. The power supply can be connected to the board through the power jack, and the power can be regulated using the onboard voltage regulator. The board can also be powered through the USB port, but the voltage supplied through the USB port is limited to 5 volts.
Programming
The Arduino Due can be programmed using the Arduino IDE, which is available for free download. The board can be programmed using the USB port, and the code can be uploaded to the board using the USB port. The board can also be programmed using the JTAG port, which is available on the board.
Arduino Mega and Arduino Due
Arduino Mega and Arduino Due are two of the most popular boards from the Arduino family. Both of these boards are equipped with powerful processors and are capable of handling complex tasks. The Arduino Mega is powered by an Atmel AVR microcontroller and has a clock speed of 16 MHz. It has a total of 54 digital I/O pins, 16 analog inputs, 4 UARTs, and a 16-bit timer/counter. The Arduino Due, on the other hand, is powered by an ARM Cortex-M3 processor and has a clock speed of 84 MHz. It has 54 digital I/O pins, 12 analog inputs, 4 UARTs, and a 32-bit timer/counter.
Clock Speed
The clock speed of the Arduino Due is significantly higher than that of the Arduino Mega. This means that the Arduino Due can execute more instructions in a shorter amount of time, making it faster and more efficient than the Arduino Mega. The higher clock speed also allows the Arduino Due to process data more quickly and accurately.
Memory
The Arduino Mega has a total of 256 KB of flash memory, 8 KB of SRAM, and 4 KB of EEPROM. The Arduino Due, on the other hand, has a total of 512 KB of flash memory, 96 KB of SRAM, and 4 KB of EEPROM. This means that the Arduino Due has more memory than the Arduino Mega, allowing it to store more data and process more complex tasks.
Current Ranges
The Arduino Mega has a maximum current draw of 200 mA from its I/O pins, while the Arduino Due has a maximum current draw of 3.3 A from its I/O pins. This means that the Arduino Due is capable of handling more power than the Arduino Mega. This makes the Arduino Due more suitable for applications that require more power, such as motor control and robotics.
The Arduino Due is a powerful and efficient prototyping board, which offers a lot of features and advantages over the Arduino Mega. The board has 54 GPIO pins, and it can be powered by an external power supply or a Li-Po battery. The board can be programmed using the Arduino IDE, and the code can be uploaded to the board using the USB port or the JTAG port.
Overall, the Arduino Due is more powerful and efficient than the Arduino Mega. It has a higher clock speed, more memory, and a higher current draw. This makes the Arduino Due more suitable for applications that require more power and processing power.
