Boardview for the Apple A1534 MacBook logic board 820-00244, with the 08 suffix in the name likely being the board revision. Apple uses 820-xxxxx numbers for its logic boards, printed on the PCB near the edge. The 82.6 KB zip opens in OpenBoardView, FlexBV or a similar tool. It shows component locations, nets and test points for tracing power rails, checking shorts on PPBUS or similar lines, and finding parts. Confirm the 820 number on the board before relying on it.
