Arduino DUE(Compatible) R3 ARM Cortex M3 Development Board

The Arduino Due is a massive leap forward in power for the Arduino ecosystem. It is the first Arduino board based on a 32-bit ARM core microcontroller (the Atmel SAM3X8E ARM Cortex-M3).

Unmatched Speed & Power

Clocking in at 84 MHz, the Due is significantly faster than standard 8-bit boards like the Uno or Mega. With 512 KB of Flash Memory and 96 KB of SRAM, it is designed for heavy computational tasks, such as audio processing, complex algorithms, and high-speed robotics.

True Analog Output (DAC)

Unlike most Arduino boards that fake analog output using PWM, the Due features 2 x True Analog Outputs (DAC). This allows it to generate actual audio signals or precise voltage waveforms directly.

Massive Connectivity

With 54 Digital I/O pins and 12 Analog Inputs, the Due offers the same expandability as the Mega but with vastly more processing power. It also supports USB On-The-Go (OTG), allowing the board to act as a USB Host for keyboards, mice, or Android phones.

⚠️ CRITICAL VOLTAGE WARNING ⚠️

Unlike the Arduino Uno or Mega, the Arduino Due runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Connecting higher voltages, like 5V, to an I/O pin could damage the board. Please ensure your sensors and modules are 3.3V compatible.
