Boardview for Apple logic board 820-01521, the PJJ MLB, marked as a Pre-EVT2 engineering stage, compressed to 140 KB in rar. Pre-EVT data comes from early validation builds, so some part placements or references may differ from the production board. A boardview shows component locations, net names and pin connections, and is opened with tools such as OpenBoardView, FlexBV or Boardviewer. Cross-check against the schematic and the physical board before measuring, especially around areas redesigned for later revisions.
