Boardview for the HP Stream 14 on Quanta board DA0P9MB16D0, compressed in a 111 KB RAR archive, which is one of several copies. The DA0-prefixed number follows Quanta's motherboard naming pattern. Boardview files show the component placement, pin nets and test points on both sides of the PCB and open in viewers such as OpenBoardView, FlexBV or Boardviewer, depending on the contained format. Make sure the board carries DA0P9MB16D0 before using it to locate parts.
