Thanks, I find those 7 files but it didnt't solve my question because my background is too week.  I want to find out first is the pin lay out. has the top view of roboaudio.  And tell me the topleft is PWM but I don't know which one is power which one is ground which one is signal.  And the next is motor.  For what kind of motor?  What are those two pins?  Power and ground?  Then GPIO, which is signal which is ground?  Next is ATMEGA?  What is it?  How to use it?  Next is audio.  Why 6 pins? 5.1 Channel? which is which?
16 pins in UARTS,  What are they? What is ISP?  What is the 4 pins GUMSTIX for?

If you goto this page:
it mentions that the roboaudio schematics are attached.

To find the attachements, scroll all the way to the bottom of the
page, and you should see:

source history similar slides discuss 7 files attached

Click on the 7 files attaced button. The first one, labelled top shows
the locations of the various connectors. Sheets 2, 4 & 5 are the
important ones for finding out what connects up where.

Feel free to ask further questions.
