Boardview set for the Gigabyte GA-AB350-GAMING desktop motherboard, described as covering all revisions, in a 4.41 MB RAR archive. This AM4 board was issued in several PCB revisions, so pick the file matching the revision printed on your board. The layouts open in viewers such as OpenBoardView or FlexBV, showing component locations, net connectivity and test points useful for tracing CPU VRM, memory and standby rails or finding a shorted part. Mixing revisions may give wrong 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 @BoardSchematic. Enginerys does not host this file.
