Placed 2 component(s): F5, D54

flux

Work done
  • Positioned F5 and D54 at the left board-edge input area, matching the CN1/VIN entry location inferred from the provided power schematic.
  • Placed D54 directly beside F5, with its K/cathode facing the protected VINS side and A/anode oriented toward GND.
  • Verified the placement is within the board and does not introduce overlap or boundary issues.
Success criteria review
  • ✅ F5 and D54 adjacent to input connector area: Completed.
  • ✅ VIN/VINS/GND airwire shortened: Completed by moving the parts together near the input edge.
  • ❌ Remaining airwire fully routed: Not completed; one VINS airwire remains between F5 and D54.
  • ✅ ERC clean for this change: No active ERC issues were reported.
  • ❌ DRC clean for this change: Not clean yet because the remaining airwire is still reported.
Next steps
The remaining action is to route the short VINS connection between F5 and D54 on the PCB. After that, rerun the board checks to confirm the airwire is cleared.
Route VINS airwire
Widen input trace
Locate VINS airwire
