Boardview archive for a board labelled A34A at revision R2.0, packed as a 564 KB RAR; the name misspells view as veiw but clearly indicates a boardview rather than a schematic. No brand or ODM part number is given, so confirm the A34A marking and R2.0 revision on the PCB before trusting it. A boardview shows part placement, net names and pin connections, letting you locate components, follow a rail to its source and find test points while probing a short. Extract it and open the layout in a viewer such as OpenBoardView or FlexBV.
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 @ITHINKHS. Enginerys does not host this file.
