Arduino Due 是一塊基於Atmel SAM3X8E CPU的微控制器板.它是第一塊基於32位ARM的Arduino. 和之前的ArduinoMega非常類似,它有54個數字IO口(其中12個可用於PWM輸出), 12個模擬輸入口,4路UART硬件串口。但是它的時鐘頻率達到84 MHz, 還有一個USB OTG接口, 兩路DAC(模數轉換),兩路TWI。Arduino Due的區別是它的工作電壓為3.3V。IO口可承載電壓也為3.3V。因此它不兼容原來的為5V設計的Shield和外設。不恰當的連接5V電源和外設可能會燒毀Arduino DUE,請在使用前檢查好電壓。

使用32位ARM核心的Due相較於以往的使用8位AVR核心的其他Arduino更強大。

主要的差別有:

  • 32位核心在一個時鐘能處理32位的數據
  • 84Mhz的CPU時鐘頻率
  • 96 KBytes的SRAM
  • 512 KBytes的Flash
  • 一個DMA控制器, 能減輕CPU做大量運算時的壓力

Arduino Due

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.

Warning: Unlike most Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.

The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.

The Due follows the 1.0 pinout:

  • TWI: SDA and SCL pins that are near to the AREF pin.
  • IOREF: allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V.
  • An unconnected pin, reserved for future use.

Getting Started

In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE), and start to tinker with coding and electronics.
