Repair archive for the Apple MacBook Pro 13 inch 2020, model A2251, logic board 820-01949, packed as a 5.26 MB RAR file. The name does not list contents, so extract it to see whether it holds a schematic, boardview or firmware. Apple uses 820-xxxxx numbers for its logic boards, and the code is printed on the PCB for verification. Material like this is used to trace power rails, locate components and test points, and diagnose shorts. Boardviews open in tools such as FlexBV or OpenBoardView.
