Running at 84MHz with 512KB of flash and 96KB of SRAM, it is the most powerful board in the classic Arduino family and is designed for applications that demand high computational performance, large memory, and multiple hardware peripherals. Note that the Due operates at \u003cstrong\u003e3.3V logic\u003c\/strong\u003e — applying 5V to its I\/O pins will damage the board.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMicrocontroller: Atmel AT91SAM3X8E (ARM Cortex-M3, 32-bit)\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: \u003cstrong\u003e3.3V\u003c\/strong\u003e (I\/O pins are NOT 5V tolerant)\u003c\/li\u003e\n\u003cli\u003eClock Speed: \u003cstrong\u003e84MHz\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlash Memory: 512KB (no bootloader storage overhead)\u003c\/li\u003e\n\u003cli\u003eSRAM: 96KB (two banks: 64KB + 32KB)\u003c\/li\u003e\n\u003cli\u003e54 digital I\/O pins (12 PWM outputs)\u003c\/li\u003e\n\u003cli\u003e12 analog input pins (12-bit ADC — 4096 levels)\u003c\/li\u003e\n\u003cli\u003e2 DAC outputs (12-bit, true analog output)\u003c\/li\u003e\n\u003cli\u003e4 hardware UART ports\u003c\/li\u003e\n\u003cli\u003e2 TWI (I2C) interfaces\u003c\/li\u003e\n\u003cli\u003eSPI interface (header + ICSP)\u003c\/li\u003e\n\u003cli\u003eUSB OTG support via Native USB port\u003c\/li\u003e\n\u003cli\u003eProgramming USB port (SAM-BA bootloader) + Native USB port\u003c\/li\u003e\n\u003cli\u003eCAN bus interface (2×)\u003c\/li\u003e\n\u003cli\u003eInput voltage: 7–12V via DC jack\u003c\/li\u003e\n\u003cli\u003eUno\/Mega shield-compatible form factor (with 3.3V caveat)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePin Highlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital I\/O:\u003c\/strong\u003e D0–D53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePWM:\u003c\/strong\u003e D2–D13 (12 pins, 12-bit resolution)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalog In:\u003c\/strong\u003e A0–A11 (12-bit ADC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDAC:\u003c\/strong\u003e DAC0, DAC1 (true 12-bit analog output)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUART:\u003c\/strong\u003e Serial, Serial1, Serial2, Serial3 (4 hardware UARTs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPI:\u003c\/strong\u003e ICSP header + pin 10 SS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI2C:\u003c\/strong\u003e SDA1\/SCL1 (pins 20\/21) + SDA\/SCL header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAN:\u003c\/strong\u003e CANRX0\/CANTX0, CANRX1\/CANTX1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed signal processing and FFT analysis\u003c\/li\u003e\n\u003cli\u003eMulti-axis CNC and motion control with high step rates\u003c\/li\u003e\n\u003cli\u003eAudio synthesis and real-time audio processing\u003c\/li\u003e\n\u003cli\u003eIndustrial automation with CAN bus communication\u003c\/li\u003e\n\u003cli\u003eAdvanced robotics requiring fast computation\u003c\/li\u003e\n\u003cli\u003eLarge display driving and graphics processing\u003c\/li\u003e\n\u003cli\u003eData acquisition systems requiring high-resolution ADC\/DAC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.3V logic only:\u003c\/strong\u003e All I\/O pins are 3.3V.
