Apple boardview in .brd format for logic board 820-01598, project J213, as labelled in the name. Apple prints the 820 number on the MLB, so confirm it before use, since similar models use different boards. The layout lets you search any part or net, see top and bottom placement and find test points for rails such as PPBUS when isolating shorts or missing voltages. Open it in OpenBoardView or FlexBV and use it alongside the matching schematic for full diagnosis.

How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
