Boardview for the Z270X Gaming SOC desktop motherboard, revision 1.01, in TVW format at 5.76 MB; the name names no brand, but Z270 refers to the Intel chipset. TVW is a Teboview layout that needs a compatible viewer. Use it to locate VRM phases, standby circuits, the BIOS chip and other components, follow nets and choose test points while hunting a short or a missing voltage. Check the revision printed on the board matches 1.01 before trusting component positions.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
