Apple A1224 archive for logic board 820-2143, revision A, in a 1.38 MB RAR. The name provides the model and the 820- board part number, which Apple prints on the PCB and which should match before you trust the contents. The package likely contains schematic material for diagnosing power faults, following voltage rails and locating components on the board. Extract with WinRAR or 7-Zip to confirm whether a boardview is included, and check the revision letter against your board before measuring.
