Arduino BOM Bill of materials please

I have about 4 arduinos I have fried and would like to replace the suspected burned up chips. I have an Uno, Mega and ADK I need parts for. Where do I find a BOM list for these. Since it is open source I would expect this to be on the site but I have searched and cannot find one. Can someone point me in the right direction please.

There is no published BOM. You can download the reference schematics and board files from each hardware page. Which contains the same information.
