Gigabyte H310M S2 motherboard boardview, revision 1.0, in an uncompressed .tvw file of 2.21 MB. TVW layouts are opened with TVW viewer software or FlexBV and let you click on parts to see their nets and connected pins. On a desktop board this is handy for finding the VRM phases, the super I/O chip, the SPI BIOS chip and test points for standby voltages. Gigabyte prints the revision on the PCB, often near the slots, and it should read 1.0 for this layout to match the hardware in front of you.
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.
