Boardview in BRD format for the ASRock H110-M1 AR desktop motherboard, version 1.02, compressed into a 371 KB RAR. BRD layouts show the position of every part, its pins and the nets, which lets a technician trace VRM outputs, standby rails and signals to the chipset or slots and locate test points for measurements. Open it with a compatible viewer such as OpenBoardView. Check that the version printed on the PCB matches 1.02, because later revisions may move or replace components.
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 @hrtechno. Enginerys does not host this file.
