2.1 General Specifications Overview

The Arduino Due is a versatile microcontroller board designed for a wide range of applications. Powered by the
Atmel SAM3X8E ARM Cortex-M3 CPU, it offers high performance and a robust set of features, making it suitable for
complex projects. The Due's 32-bit architecture provides enhanced processing capabilities compared to traditional
Arduino boards. Designed with a similar form factor to the Arduino® Mega, it maintains compatibility with most
Arduino shields through its extensive set of I/O pins and headers. The following table summarizes the board's main
features.
