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:
Clear/discard the active auto-layout job in the Flux UI, then ask me to route again.
After routing, verify no traces cross the isolation corridor or ESP32 antenna area.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
