ASUS X402CA motherboard boardview, revision 2.1, stored as a .fz file inside a 117 KB ZIP archive. FZ is a layout format common to ASUS service material, and viewers such as OpenBoardView, FlexBV or Boardviewer can open it once it is extracted. With it a repairer can locate any component by its reference designator, follow nets across both sides of the board and pick convenient probing points when hunting a short or a missing voltage. Make sure the board revision printed on the PCB is 2.1, since layouts often shift between revisions.
