Small 50.6 KB RAR archive with a generic boardview name that states no brand, model or board number. Its contents must be checked after extraction to learn which board it covers or whether it holds a viewer tool. Boardview files map every component and net on a PCB and are used alongside schematics to locate test points, follow signals and isolate shorted parts. Once the target board is identified, compare the number and revision printed on the PCB with the file before relying on it for measurements.
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 @biosarchive. Enginerys does not host this file.
