Description
- It contains everything you need to support the microcontroller.
- Power it with an AC/DC adapter or battery to get it going
- Compatible with all Arduino shields working at 3.3 V
- Arduino board based on 32-bit ARM current microcontroller
The Arduino Due 32-bit ARM Microcontroller is a microcontroller board based on an ARM Atmel SAM3X8E Cortex-M3 processor. It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (12 of which can be used as PWM outputs), 12 analog inputs, 4 UARTs (serial ports physical), an 84 MHz clock, a connection allowing USB-OTG, 2 CAN (digital/analog converter), 2 TWI, a power socket, an SPI base, a JTAG socket, a reset button and a clear button.

The Arduino Due can be powered by the USB connection or by an external power supply. The power supply is automatically selected.
External (non-USB) power can come from an AC/DC (wall) adapter or a battery. The adapter can be connected by plugging a 2.1mm center positive plug into the power socket on the board. The connection pins of a battery can be inserted into the Gnd and Vin (input voltage) male headers of the POWER (power supply) connector.
The card can operate with an external power supply of 6 to 20 volts. If powered at less than 7 V, the 5 V pin may provide less than five volts and the board may become unstable. If it receives more than 12 V, the voltage regulator can overheat and damage the board. The recommended range is 7 to 12 volts.
The power pins are distributed as follows:
- Wine. The input voltage to the Arduino board when using an external power source (as opposed to 5V from the USB connection or other regulated power source). You can supply voltage through this pin, or, if power comes through the electrical outlet, access it through this pin.
- 5V . The pin outputs regulated 5 V from the board regulator. The board can be powered with power from the DC power jack (7 to 12 V), the USB connector (5 V), or the VIN pin of the board (7 to 12 V). Supply voltage across the 5 or 3.3V pins bypasses the regulator and can damage your board. We do not recommend it.
- 3.3V . A 3.3 V power supply generated by the integrated regulator. The maximum current flow is 800 mA. This regulator also provides power to the SAM3X microcontroller.
- GND . The Earth (ground) pins.
- IOREF . This pin on the Arduino board provides the reference voltage at which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable the voltage converters on the outputs to work at 5 or 3.3 V.
