ARDUINO DUE AT91SAM3X8E ARM Cortex-M3 Board

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.

Main Features:

• 54 digital input/output pins (of which 12 can be used as PWM outputs)
• 12 analog inputs
• 4 UARTs (hardware serial ports)
• 84 MHz clock
• USB OTG capable connection
• 2 DAC (digital to analog)
• 2 TWI
• Power jack
• SPI header
• JTAG header
• Reset button
• 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 an 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.

Pinout Details:

• 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
• An unconnected pin, reserved for future use
