Apple logic board 820-03400 revision A boardview, packed as a 292 KB ZIP that should contain a CAD-format layout. The name marks it as a BDV with a .CAD file inside. Apple uses the 820-xxxxx numbering for its logic boards, and the number is printed on the board itself, so compare it before use. Technicians use such layouts to locate components, check nets for shorts to ground and find measuring points. CAD boardviews open in FlexBV, OpenBoardView and comparable tools once extracted.
