ESP32 Relay Automation PCB Design
Thought for 3 sec
Work done
- Updated the remaining relay-module pads to SMD/no-drill geometry:
RELAY_12V/RELAY_GNDare 6.0 × 6.0 mm, andRLY_IN1..RLY_IN8are 3.0 × 4.0 mm, all Top-side withholeSize = 0.0 mm. - Re-optimized the top-side placement; the earlier center-right congestion is cleared and the layout now reports enough routing space.
- Added the LM2596 warning text: “SET LM2596 TO 5.0V BEFORE CONNECTING ESP32”.
- Enabled the bottom-layer GND fill configuration on the
GNDnet with 0.3 mm clearance behavior. - Verified
U1relay-driver signal connectivity and confirmed all placed components remain on the Top layer.
- The board is still unrouted: the latest check reports active airwires. I could not complete the automatic routing step in this run, so final production signoff cannot be marked complete yet.
- Run/enable routing for the board, then re-check airwires, dangling traces, floating copper, overlaps, and missing footprints. After routing is complete, I can do the final production-readiness pass and generate manufacturing outputs.
