WiFi PC Power Switch Schematic

Updated the PCB layout placement: added R3 10k pull-down, added 2 mounting holes, resized to 80 × 55 mm, placed ESP32/control side left, PC817 center, and J1 at the right board edge with left-to-right flow.
Open items:
  • Routing is not completed because the autorouter is blocked by an active completed layout job in Flux.
  • Airwires remain until routing can run.
  • Pin mapping is verified correct: GPIO5 → R1 → PC817 AN, PC817 CAT → ESP32_GND, PC817 COL/EM → J1.
Suggested next steps:
  1. Clear/discard the active auto-layout job in the Flux UI, then ask me to route again.
  2. After routing, verify no traces cross the isolation corridor or ESP32 antenna area.
  3. Then run final DRC before fabrication export.
I cleared the layout job. Please run routing again.
I’ll rerun the routing pre-check, start autorouting, then verify remaining airwires and layout issues.
Routing pre-check passed: the board is valid and ready for autorouting.
Open items:
  • I can’t start the autorouter now because your account currently has no available ACUs, so AI execution is paused.
  • PCB traces are still not routed; airwires likely remain.
Suggested next steps:
  1. Add/restore ACUs, then ask me to “run autorouting again.”
  2. After routing, I’ll verify airwires, isolation gap, ESP32 antenna clearance, and terminal-side routing.
  3. Then we can run final DRC before fabrication export.
