Tethered Mini Drone Design


Routing preflight found C2 and D1 inside the bottom-left mounting-hole keepout. Routing cannot preserve both the approved placement and the required Ø8 mm mechanical clearance; moving those two parts is the recommended fix.
The autorouter connected 125 of 134 initial airwires, and surgical routing reduced the remainder to six. The remaining pins are physically blocked by the approved placement/existing copper, so further retries without changing placement or deleting working routes would not converge; I’m running the final DRC summary now.
Routing is substantially complete: 753 trace segments and 154 vias were added, with no overlapping-copper, via-in-pad, dangling-trace, or redundant-trace errors.
Open items
  • 6 airwires remain:
    • EFUSE_OVP: U2 OVP → R5
    • 3V3: U4 VOS → existing 3V3 via
    • Four ground-plane connections around U6, C13, and R3
  • These remained blocked after two targeted attempts; finishing them requires local copper rip-up and likely small placement adjustments.
  • Non-blocking placement advisories remain for five decoupling loops and the U3→L1 switch-path detour.
Suggested next steps
  1. Authorize surgical movement around U2/U4/U6 and local trace rip-up to clear the six airwires.
  2. Re-run full DRC and power-integrity checks.
  3. Reconcile the routed PCB against the frame and USB-C cable clearance.
