Schematic for the Apple MacBook Pro 13-inch 2020, model A2251, logic board 820-01949-A, in PDF inside a RAR of about 3 MB. Apple numbers its boards 820-xxxxx, and the letter suffix gives the revision. Technicians use these pages to follow power rails, identify sequencing stages and trace signals around the T2 chip, charging and USB-C circuits. Open the PDF in any reader with search, which helps find net names. Check the 820 number on the board before relying on it.
