Boardview for the ASUS E403SA laptop motherboard, revision 2.1, compressed into a 105 KB RAR archive. A boardview shows component placement, part references, nets and test points on both sides of the PCB, which helps locate parts quickly while measuring rails or hunting a short. It opens in programs such as OpenBoardView, FlexBV or ASUS-compatible viewers depending on the internal format. Confirm the board revision marked on the PCB is 2.1, since layouts can differ between revisions.
