Arduino Due, the first Arduino board built on a 32-bit ARM Cortex-M3 core. Powered by the Atmel SAM3X8E microcontroller, the Due offers exceptional speed, memory, and peripheral options—perfect for advanced applications in robotics, audio processing, real-time data acquisition, and more. With 54 digital input/output pins (including 12 PWM outputs), 12 analog inputs, and 2 DAC outputs, the Arduino Due provides a wide range of interfacing capabilities. It also supports 4 hardware UARTs, USB OTG, SPI, TWI (I2C), and includes a JTAG header for debugging. Ideal for high-speed embedded applications, the Due features an 84 MHz clock, 512 KB Flash memory, and 96 KB SRAM (divided into 64 KB and 32 KB banks). It follows the Arduino 1.0 pinout, including dedicated SDA/SCL pins, IOREF, and supports shields compatible with 3.3V logic. ⚠️ Note: Unlike most Arduino boards, the Due operates at 3.3V logic. Applying more than 3.3V to any I/O pin may damage the board.
