2 Features
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.

5.2 Power Specification
Property Min Typ Max Unit
Supply voltage 7.0 - 12 V
Permissible range 6.0 - 16 V
Safety Note: Unlike most traditional Arduino boards, the Arduino Due board runs at 3.3 V. Keep in mind the
maximum voltage that the I/O pins can tolerate is 3.3 V. Applying voltages higher than 3.3 V to any I/O pin
could damage the board.
