Revised intro to better explain why Printrbot released yet another RepRap motherboard, and what Printrboard brings to the table.
Added images and complete software documentation for bootloader and firmware, including firmware flashing process in Windows. Still need Linux and Mac instructions. Special thanks to Lincomatic for sorting out all AT90USB bootloader options, and for providing several firmware development forks before Printrboards are even on the market.
Added quick hardware overview with pinouts for all major headers.
Added screenshots of current schematic and board layout. Began Revision History section.

Do we want to keep track of major (letter) releases only, or also keep track of minor updates like Rev F4? The schematics on this page are out of date and don't match currently shipping Printrboards/bots.
When programming a new bootloader and changing fuse settings, need to add -u command in avrdude (turns off safemode), at least for the Pololu AVR programmer, didn't work until I did this. If this can be confirmed for other people, add to main article.

Corrected motor pinout table to match Allegro terminology, schematic, and PCB layout. Prior "Note" that pointed out the polarity reversals was removed when table was updated.
