Position of the Beagleboard Expansionheader


i want to build a beagleboard expansion board like the zippy boards
and want to know if someone could give me the dimensions of the LCD-
Header on a
expansion-board which has the same size as the beagleboard?

You can look at the System Reference Manual for the Rev C4 position. The actual part numbers for the connectors are also called out in the System Reference Manual. If you download the datasheets for the respective manufacturers, they give the dimensions of the connectors. The location of pin 1 is also found in the System Reference Manual. So, in short, read the System Reference Manual.
