Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.
The adapter can be connected by plugging a 2.1mm plug into the board's power jack. The power source is selected automatically.Įxternal power can come either from an adapter or battery. The Arduino Due can be powered via the USB connector or with an external power supply.

You can build your own board using the following files: An unconnected pin, reserved for future use.This enables shield compatibility with a 3.3V board like the Due and boards which operate at 5V. IOREF allows an attached shield with the proper configuration to adapt to the voltage.TWI SDA and SCL pins that are near to the AREF pin.The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the Arduino pinout.
The board contains everything needed to support the microcontroller simply connect it to a computer with a cable or power it with a adapter or battery to get started. Applying voltages higher than 3.3V to any I/O pin could damage the board. The maximum voltage that the I/O pins can tolerate is 3.3V. Warning Unlike most Arduino boards, the Arduino Due board runs at 3.3V. 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. It is the first Arduino board based on a ARM core microcontroller. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM CPU. With 54 digital input/output pins, 12 analog inputs, it is the perfect board for powerful larger scale Arduino projects. The Arduino Due is the first Arduino board based on a ARM core microcontroller.
