After a long wait, the Arduino Due is finally available. The Due is based on an Atmel ARM Cortex M3 running at 84 Mhz, bringing a 32 bit processor to the Arduino world. Rumors and early sightings have been floating around for a while but the official announcement was made in the Arduino blog today. The only downside to all that new power is that, being ARM-based, a lot of existing AVR code won't be compatible without some work. There are a few other caveats, like getting used to the 3.3 volt levels on the I/O pins. Using 5 volts can damage the board. Like previous Ardunio boards, the design is open source hardware. So download the schematic, Eagle PCB files, and pin mappings and get to work on a robot controller! The price is $49. Read on for full specifications of the new Arduino Due board.
