Wiring serial interfaces?  Bluetooth / USB

I want to make my own Arduino board with integrated accelerometers and gyros. However, I'm not sure how to wire up the USB to serial adapter chip. Is there a schematic of the Arduino board along with a list of materials?

I'm also interested in doing the same thing and utilizing a blue tooth serial port.


On this page:


there is a "Schematic & Reference Design" section which has the schamtics in .pdf and Eagle formats.

Similarly here for the bluetooth version...
