Schematic for the MacBook Pro 13-inch 2020 model A2289, the two-Thunderbolt-3 Touch Bar version, on logic board 820-01987, packed into a 1.83 MB RAR. Apple marks its logic boards with 820- numbers, so check the code on the PCB matches before use. The extracted drawing opens in a PDF reader and helps trace power rails, the USB-C power path and signals when diagnosing a board that will not turn on. Pairing it with the matching boardview makes finding components much easier.
