The Duce is a general purpose board for Atmel's at90usb162 and atmega8/16/32u2. Combined with open source code it can be used to easily create usb solutions. With relatively large components (tqfp, 603) the board is an excellent place to learn surface mount soldering as well as an inexpensive introduction to Atmel's 90usb family of micro controllers. Incidentally the duce uses the same micro controller as the new arduino uno. In fact the firmware for the uno is based on Dean Cameras rewrite of the original Benito firmware.
After many iterations of trying new design ideas through the DorkbotPDX Group PCB Order the new design is available through the suspect devices website.
A secret cache of the original Benito's was found when going through the lab. If you want to build one you should be able purchase them through our Etsy Store.
The current design brings out port d of the processor in an stk500 format.
And if you use the cable that comes during the induction (where brown is pin 1) then this cable will connect you to the dorkboard perfectly...
Origional Benito Pinouts.
The official firmware for the duce is Paul Stoffregon's alternative software. As described in the comment below.
