Boardview file for Compal platform PAR00, board LA-6601P revision 1.0, marked A00, with the BDV tag confirming the boardview content. Boardview files show component placement, part names, nets and test points, which helps when tracing power rails, finding shorts or locating a missing part. They are opened with viewers such as OpenBoardView, FlexBV or Boardviewer, depending on the exact format inside. Check that the LA number and revision silkscreened on the PCB match before relying on pin locations.
