Boardview for the Apple MacBook A1278 logic board 820-2530, project K24. Apple identifies logic boards by 820-xxxx numbers, and this zip of 113 KB contains a layout file for viewers like OpenBoardView or FlexBV. It lets a technician locate components by reference, follow nets to the SMC, charger and power rails, and find test points when chasing a short or no-power fault. Confirm that the 820-2530 number is printed on your board, as other A1278 years use different boards.
