This page is generated from the board file itself, so the map above is the manufacturer layout rather than a redrawing of it. The board carries 4,598 components and 3,390 named nets across 16,415 pads, with 990 test and probe points marked in amber for when you want to measure rather than desolder. About 100% of the components are surface-mount, so the top and bottom side filter is usually the difference between finding a part in one pass and searching both faces.
This is the logic board fitted to the A1990 (2018 / 2019), covering the 2018–2019 production run. Check the board number before you order parts: several of these machines shipped with more than one board revision, and a component taken off the wrong revision frequently has the same designator and a different footprint.
Frequently asked about the MacBook Pro 15-inch A1990 (2018–2019) (820-00923)
What board number is the MacBook Pro 15-inch A1990 (2018–2019) (820-00923)?
The MacBook Pro 15-inch A1990 (2018–2019) (820-00923) uses logic board 820-00923, the board fitted to the A1990. There is more than one revision of some of these boards, so check the number on the board itself against the one on this page before you order a part — a component from a different revision will often not fit or will not reference the same nets.
How many components and nets are on the MacBook Pro 15-inch A1990 (2018–2019) (820-00923)?
The board file records 4,598 components (4,581 surface-mount, 17 through-hole), 3,390 named nets and 16,415 pads, plus 990 test and probe points. The board measures 289.48 × 103.73 mm. Roughly 100% of the parts are surface-mount, which is why the top and bottom side filter matters — a lot of this board is only reachable from one face.
How do I use this MacBook Pro 15-inch A1990 (2018–2019) (820-00923) boardview?
Type a designator such as a component reference, or a net name, into the search box above. A net name takes priority and highlights every pad on that net across the whole board. Clicking a component outlines it in white and lists every pad it has with the net each one belongs to; clicking one of those nets jumps the highlight to the whole rail. Use the side filter to isolate the top or bottom face, and the designator toggle to hide the reference text when you are zoomed out.
Is a schematic available for the MacBook Pro 15-inch A1990 (2018–2019) (820-00923)?
Not yet. The boardview is complete and interactive on this page, and the board file itself is downloadable, but we have not got a verified schematic for this revision. We would rather show the gap than link to a schematic that belongs to a different board revision — on a multi-revision machine those files look right and are wrong in exactly the places that cost you an afternoon.
Can I download the MacBook Pro 15-inch A1990 (2018–2019) (820-00923) boardview file?
Yes. The original 813 KB BoardView file is linked below under downloads, named macbook-pro-15-inch-a1990-820-00923.brd. Open it in BoardViewer or any other tool that reads the .brd format. The interactive viewer on this page is for looking things up quickly; the .brd is what you want when you are at the bench with the board on the mat.
