Arduino Due Board – 32-bit Microcontroller for Advanced Arduino Projects
The Arduino Due is the first Arduino board built on a 32-bit ARM Cortex-M3 microcontroller (Atmel SAM3X8E), bringing a major leap in processing power, memory, and connectivity compared to earlier AVR-based boards. With its higher clock speed and extended peripherals, the Due is designed for advanced applications in robotics, automation, signal processing, and data-intensive projects.
Featuring 54 digital input/output pins (12 PWM), 12 analog inputs, 2 DACs, and 4 hardware UARTs, the Due offers wide flexibility for connecting sensors, actuators, and communication modules. Its USB OTG capability, SPI and JTAG headers, along with built-in reset and erase buttons, make it versatile for development and debugging.
Important: Unlike most Arduino boards, the Due operates at 3.3V logic levels. Supplying voltages higher than 3.3V to I/O pins can damage the board.
The board includes everything you need to get started: simply power it through a micro-USB cable, a 7–12V adapter, or a battery. It is also compatible with Arduino shields that support 3.3V operation and follow the Arduino 1.0 pinout standard.
