There are a few very neat features in the DUE, namely a USB On The Go port to allow makers and tinkerers to connect keyboards, mice, smartphones, etc...A few DUE boards have already made it into the hands of important people in the Arduino community, it seems.
The PDF handed included:
The Arduino Due is the newcomer microcontroller board in the Arduino boards family. lt's the first board based on a 32 bit processor (Atmel SAM3X8E ARM Cortex-M3 N/CU), which improves all the standard Arduino functionalities and adds manv new features.
The arduino DUE offers 54 digital input/output pins (of which 16 can be used as PWM outputs, with selectable resolution), 12 analog inputs with 12 bits of resolution, 4 UARTs (hardware serial ports), two DAC (digitalto analog converter) outputs, an 84 MHz crystal oscillator, two USB connections, a power jack, an ICSP header, a JTAC header, and a reset button.
The Due has two micro USB connectors: one intended for debugging purposes and a second one capable of acting as a USB host, allowing external USB peripherals such as mouse, keyboards, smartphones, etc. to be connected to the Arduino Due.
