Hi Richard, See here how i want to make my next board based on 4550: http://sites.google.com/site/funlw65/electronics/jaluino-pinguino-28-pins-starting-bo/freejalduino-mega?pli=1
It have a lot of bridges but is because of Arduino shield compatibility. It can be made at home and also as a double-sided pro board (through hole components). Is also designed to be programed with Pinguino (but Pinguino must be adapted to it - is not hard to do). Of course, I'm not an expert. The design can be much better...
