writes "After six years in the making, the Arduino Due is finally becoming available and, with a price tag of $49, is bound to give a boost to the platform.The Due, which means 2 in Italian and is pronounced "doo-eh", replaces the 8-bit, 16MHz Uno by a 32-bit, 84MHz processor board that also has a range of new features — more memory, a USB port that allows it to pretend to be a mouse or a keyboard say, 54 I/O pins and so on — but what lets you do more with it is its speed and power. The heart of the new Arduino Due is the Atmel SAM3X8E, an ARM Cortex-M3-based processor, which gives it a huge boost in ADC performance, opening up possibilities for designers. The theoretical sampling rate has gone from the 15 ksps (kilosamples per second) of the existing boards, the Arduino Uno, Leonardo, and Mega 2560, to a whopping 1,000 ksps.
What this all means is that the Due can be used for much more sophisticated applications. It can even play back wav files without any help. Look out for the Due in projects that once would have needed something more like a desktop machine."Link to Original Source
