ArduinoDue

Overview
The Arduino Due is the newcomer microcontroller board in the Arduino boards family. It’s the first board
based on a 32 bit ARM core processor, the Atmel SAM3X8E ARM Cortex-M3 MCU, that improve all the
standard Arduino functionalities and add more new features.
It offer 54 digital input/output pins (of which 16 can be used as PWM outputs, with selectable resolution), 12
analog inputs with 12 bit of resolution, 4 UARTs (hardware serial ports), and two DAC outputs (digital to
analog converter), 84 MHz crystal oscillator, two USB connections, a power jack, an ICSP header, a JTAG
header, and a reset button. The maximum voltage that the I/O pins can provide or tolerate is 3.3V. Providing
higher voltages, like 5V to an input pin could damage the board.
The Due has two usb connectors, the one with the micro-usb B connector is the native one capable to act as an
usb host, that means you can connect compatible external usb peripherals to the board, such as mouse,
keyboards, smartphones. While the other ubs port with the type A connector is intended for debugging
purposes.
