Arduino DUE 義大利原廠進口 Due 尋求更強悍的 Arduino

商品說明

Arduino DUE為您的大型項目提供了32位微控制器的強大功能
Arduino DUE工作電壓為3.3V，具有54引腳數字I / O（12 PWM），12個模擬輸入，84 MHz時鐘，2個DAC（數模轉換）和一個JTAG，用於直接編程和調試。

Arduino Due是基於Atmel SAM3X8E ARM Cortex-M3 CPU（數據表）的微控制器板。它是第一款基於32位ARM核心微控制器的Arduino板。它有54個數字輸入/輸出引腳（其中12個可用作PWM輸出），12個模擬輸入，4個UART（硬件串行端口），84 MHz時鐘，USB OTG連接，2個DAC（數字到模擬） ，2個TWI，一個電源插孔，一個SPI接頭，一個JTAG接頭，一個複位按鈕和一個擦除按鈕。

警告：與其他Arduino板不同，Arduino Due板的電壓為3.3V。 I / O引腳可承受的最大電壓為3.3V。向I / O引腳提供更高的電壓（如5V）可能會損壞電路板。

電路板包含支持微控制器所需的一切;只需使用micro-USB線將其連接到計算機，或使用AC-DC適配器或電池為其啟動。 Due與所有Arduino屏蔽兼容，工作電壓為3.3V，符合1.0 Arduino引腳排列。

Due遵循1.0引腳：

TWI：靠近AREF引腳的SDA和SCL引腳。
IOREF引腳允許使用適當配置的連接屏蔽以適應電路板提供的電壓。這使屏蔽與3.3V電路板兼容，如基於Due和AVR的電路板，工作電壓為5V。未連接的引腳，留作將來使用。
Due有一個32位ARM內核，可以勝過典型的8位微控制器板。最顯著的差異是：

32位內核，允許在單個CPU時鐘內對4字節寬數據進行操作。
CPU時鐘為84Mhz。
96 KB的SRAM。
代碼為512 KB的閃存。
一個DMA控制器，可以減輕CPU執行內存密集型任務的負擔。

Arduino DUE gives you the power of a 32-bit microcontroller ready for your larger projects

The Arduino DUE works at 3.3V, has 54-pin digital I/O (12 PWM), 12 analog inputs, a 84 MHz clock, 2 DAC (digital to analog conversion) and a JTAG for direct programming and for debugging.

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). 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 other Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an 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.
• The IOREF pin which 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.

The Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are:

• A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock.
• CPU Clock at 84Mhz.
• 96 KBytes of SRAM.
• 512 KBytes of Flash memory for code.
• a DMA controller, that can relieve the CPU from doing memory intensive tasks.
