A Propeller Robot Controller board is available if you want to modify an existing BOE-BOT. Have a look at: http://www.wulfden.org/PRC/
I seem to recall that the holes in the board do not line up with mounting holes on the BOE-Bot chassis but that does not have to be a big problem if you own a drill.
You can easily use a piece of plastic or printed circuit board cut to fit with holes drilled at the corners and mount the Propeller Demo Board using two layers of double-sided foam tape. Works great! The long double-sided header pins that come with the servo extension cables from Parallax fit nicely in the breadboard.
