Boardview in BRD format for Apple logic board 820-03286, labelled with A3114, compressed to 3.71 MB. BRD layouts open in viewers such as OpenBoardView, FlexBV or similar programs. They show every component, pin and net, which makes it easy to locate test points and measure diode readings when hunting a short. Apple's 820-xxxxx numbering is printed on the PCB, so confirm the number matches before probing. Use it together with the schematic of the same board.
