아두이노팀의  첫번째 ARM기반 아두이노 보드입니다.  Cortex M3 ARM 사용으로 기존 아두이노 보다 강력한 하드웨어 성능을 제공합니다. 개발환경은 종전과 같은 Arduino IDE 환경을 사용할 수 있습니다.(현재 베타버전) 

주의.

본 보드는 3.3V 로 구동되며  IO(입출력)전압은 3.3V 이내만 허용됩니다. 그보다 높은 전압 값(가령 5V)을 입력시 보드가 파손되오니 이점 주의바랍니다.

Description:

The Due is Arduino's first ARM-based Arduino development board. This board is based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the familiar Arduino IDE. It increases the computing power available to Arduino users keeping the language as compatible as possible so that many programs will be migrated in a matter of minutes!

The Arduino Due has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a 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. There are also some cool features like DACs, Audio, DMA , an experimental multi tasking library and more.

To compile code for the ARM processor, you'll need the latest version of the Arduino IDE: v1.5 (After a period of testing and debugging this will replace the 1.0.1 IDE altogether)

Because of the limitations of system voltage imposed by the Atmel SAM3X8E, Arduino shields that are based on the 5v models won't work properly. All the shields that fully implement the Arduino R3 layout are compatible straight away (like the Arduino WiFi shield and Ethernet Shield) but other shields might not be compatible. Be careful when you're plugging stuff in!

Note:

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.
