LED Blinker Circuit Design

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.
