Boardview of the Gigabyte GA-H81-D3 motherboard, revision 1.01, provided in the .tvw format at about 2.5 MB. The board uses Intel's H81 chipset, and the file maps parts and nets so a technician can trace standby and main power rails, check CPU VRM MOSFETs, locate the BIOS flash and find measurement points for a short to ground. Open it with TeboView or another TVW-capable viewer. Gigabyte revisions such as 1.0 and 1.01 can differ, so match the number printed on the board first.
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.
