Difference Between Arduino Due vs Mega
Arduino Due is considered the type of Arduino board that relies on a 32-bit ARM-type core microcontroller. The Arduino due contains 54 digital inputs, output pins, and twelve analog inputs. The Arduino Due board is mainly used for projects with large-scale scope. The Arduino Mega is another type of Arduino board that uses the ATmega2560 microcontroller. There are 54 input pins and output pins, sixteen analog inputs, and 14 pins used as PWM. The mega board contains all the components required for any type of microcontroller.
