CM5 Handheld Voice Assistant Project

flux

I’ll organize the PCB for a compact handheld layout: set/confirm board constraints, place the CM5 centrally, group power/input parts, cluster UI/audio/display parts, then route and run layout checks.

flux

Organized the PCB into a compact 70 × 120 mm, 4-layer handheld layout: CM5 centered, USB-C/power at the bottom, microphones at the top, buttons on the right edge, display FPC near the CM5, and audio/power passives grouped near their ICs. Auto-routing completed and added 762 routing nodes.
Estimated time saved vs. manual EDA workflow: ~6–10 hours.
Open items:
  • Final checks still show unresolved routing issues: mainly USB D+/D−, MIPI DSI pairs, some GND/audio connections, dangling traces, and overlapping copper.
  • The charger footprint has a pad conflict that likely needs footprint/symbol cleanup.
  • The high-current boost converter and battery connector are still placeholders/not finalized, so the power layout is not production-ready.
Suggested next steps:
  1. Fix the U3 charger footprint pad conflict.
  2. Manually route/clean USB and MIPI differential pairs.
  3. Delete/repair dangling and overlapping autoroute traces.
  4. Add the real boost converter and battery connector, then reroute the power section.
