Boardview in a 154 KB ZIP for Quanta board DA0NJIMB8C0, used in an ASUS laptop. Quanta labels boards with a DA0 prefix code printed on the PCB. A boardview shows component placement, nets and test points, letting you locate parts and follow signals across both sides of the board. Viewers such as OpenBoardView or FlexBV open most formats. The name does not state a revision, so check the PCB marking and compare part locations before trusting it for measurements.
