Thought
Work done
- Repacked the PCB placement while preserving the existing architecture, keeping connectors on edges, and keeping U4 at the top edge with antenna overhang.
- Tightened placement again to pull U4 farther inside the board and add local clearance around U6.
- Verified the layout envelope and documented the cleanup state in Design Notes.
Success criteria review
- ❌ No remaining PCB airwires: review still reports 59 airwires.
- ❌ Overlapping copper eliminated: review still reports 4 overlapping-copper errors tied to U6.
- ❌ Board dimensions strictly comply with 60 mm x 45 mm: component bounds improved to 57.75 mm x 49 mm, so height is still over the 45 mm limit.
- ✅ Overall system architecture was preserved during placement cleanup.
- ❌ DRC/ERC fully clean: the layout review still shows airwire and copper-overlap errors, and ERC still shows floating pin U1
LX.
Next steps
I could not finish the remaining plan because this session is blocked from further project edits. The next concrete actions are:
- compress the vertical placement another 4 mm while preserving U4 antenna clearance,
- localize and clear the copper short at U6,
- then route the remaining airwires and re-run validation.
If you resume with edit access, I can continue from this exact state.
