- Hand-route the 6 remaining unrouted airwires and clean up floating copper on Cortex v0 BLE Audio Wearable, ensuring the preservation of U1 Raytac (RF keepout), PZ1 bottom-center placement, and the six U3 EPAD overlap exceptions.
-
Route the specific airwires:
- Hand-route U1 P0.27 haptic motor enable to Q1 gate on the top layer using standard signal width.
- Route the PZ1 piezo signal from terminal P2 on the bottom side through C11 to the non-inverting input of U5 MCP6001 with a short, isolated trace away from high-dV/dt nets (LED data, QSPI clock, USB, etc.).
- Identify the GND_3 airwire and connect it to the nearest available ground via.
-
Clean up copper and resolve fill/stitching issues:
- Regenerate the inner ground plane copper pour to resolve the three c37d412e fill/stitching items and add stitching vias as needed.
- Delete the floating copper fragments: Trace 1692, 5ef0, 60f6, 7849, c80a, and e493.
-
Final verification:
- Rerun airwire and DRC checks.
- Confirm that only the six documented U3 EPAD overlap exceptions remain.
- U1 P0.27 is routed to Q1 gate on top layer with correct trace width.
- PZ1 piezo signal correctly routed through C11 to U5 MCP6001 non-inverting input with required isolation.
- GND_3 is connected to ground via.
- Ground plane copper pour is updated, fill/stitching issues resolved, and all specified floating copper fragments are deleted.
- Post-fix DRC and airwire checks indicate only the accepted U3 EPAD exceptions remain.

#Goal
- Hand-route the 6 remaining unrouted airwires and clean up floating copper on Cortex v0 BLE Audio Wearable, ensuring the preservation of U1 Raytac (RF keepout), PZ1 bottom-center placement, and the six U3 EPAD overlap exceptions.
#Implementation plan
1. Route the specific airwires:
1. Hand-route U1 P0.27 haptic motor enable to Q1 gate on the top layer using standard signal width.
2. Route the PZ1 piezo signal from terminal P2 on the bottom side through C11 to the non-inverting input of U5 MCP6001 with a short, isolated trace away from high-dV/dt nets (LED data, QSPI clock, USB, etc.).
3. Identify the GND_3 airwire and connect it to the nearest available ground via.
2. Clean up copper and resolve fill/stitching issues:
1. Regenerate the inner ground plane copper pour to resolve the three c37d412e fill/stitching items and add stitching vias as needed.
2. Delete the floating copper fragments: Trace 1692, 5ef0, 60f6, 7849, c80a, and e493.
3. Final verification:
1. Rerun airwire and DRC checks.
2. Confirm that only the six documented U3 EPAD overlap exceptions remain.
#Success criteria
- U1 P0.27 is routed to Q1 gate on top layer with correct trace width.
- PZ1 piezo signal correctly routed through C11 to U5 MCP6001 non-inverting input with required isolation.
- GND_3 is connected to ground via.
- Ground plane copper pour is updated, fill/stitching issues resolved, and all specified floating copper fragments are deleted.
- Post-fix DRC and airwire checks indicate only the accepted U3 EPAD exceptions remain.
