Arduino Due Arduino

DESCRIPTION

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 improves all the standard Arduino functionalities and adds more new features.

It offers 54 digital input/output pins (of which 12 can be used as PWM outputs, with selectable resolution), 12 analogue inputs with 12-bit resolution, 4 UARTs (hardware serial ports), and two DAC outputs (digital to analogue 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 AB connector is the native one capable to act as a USB host, which means you can connect compatible external USB peripherals to the board, such as mice, keyboards, and smartphones. While the other USB port with the type B connector is intended for debugging purposes.
