Arduino A000062 Board Due Core

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. 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.
