32bit Arduino goodness arrives on the bech in the form of Due thanks to Element14!

Manufacturer: 

The Arduino Due has been out for a little bit now and we finally have one on our workbench! Element14 has sent me a Due so I can create some content for their Arduino section in the element14 commuinity. I will be working alongside element14 vets such as Jeremy Blum, and Dave Young to bring everyone some awesome information and content based around the Arduino Due. For my part I will be writing a blog post or two as well as building a RAMPS style RepRap / 3D Printer controller board with some exciting new features. If there is anything you would like to know, or see the Due do, please contact me or leave a comment and I will try to work it in.

Arduino Due

 

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 12 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 AB 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 USB port with the type B connector is intended for debugging purposes.
