Work done
  • Reviewed the current schematic and layout state for U1, U2, P1, P2, passives, test points, and mounting holes.
  • Confirmed the actual blocker in the layout: the board still contains many legacy route segments on invalid inner layers from an older 4-layer state, plus overlapping and floating copper.
  • Reapplied conservative board-level layout rules for the current 2-layer board and removed one stale layout-level layer override.
  • Verified that manufacturing MPN and footprint checks are clean, but PCB DRC is still not clean.
Success criteria review
  • ✅ Identified the root cause of the remaining PCB issues.
  • ✅ Verified the project is using a 2-layer stackup in the active layout view.
  • ❌ Component placement was not completed in this session.
  • ❌ Airwires, floating copper, and overlapping copper were not cleared.
  • ❌ The antenna keepout and final silkscreen placement were not completed.
Next steps The next step is to remove or regenerate the legacy invalid-layer route segments, then place U1 at the board edge with antenna clearance, place the remaining components per the placement plan, and re-run DRC until airwires and copper errors are resolved. I cannot continue that execution in this session.
