Boardview for the Gigabyte GA-B150M-DS3H desktop motherboard, revision 1.0, saved in the TVW format, 2.78 MB. TVW layouts open in Teboview and in some multi-format viewers. Such a file shows component placement on both sides of the board, part designators and net connections, so a technician can trace a power rail, find test points or isolate a shorted capacitor around the VRM or chipset. Check that the revision silkscreened on the board is 1.0, as Gigabyte layouts change between revisions.
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.
