ESP32-S3 Firmware Refinement


Routing started and completed a main pass:
  • Added 199 routing nodes.
  • Renamed switches to RST_SW and BOOT_SW.
  • Fixed the 12V regulator escape-width routing blocker.
  • Set USB D+/D− nets to 0.15 mm trace width.
Remaining review issue: 4 USB D+/D− airwires at the USB-C connector/ESD path. A second cleanup routing pass added 0 nodes, so these likely need manual/targeted USB routing or a small USB connector/ESD placement adjustment.
move the j2 to the top left edge but keep a clearance of around 0.73cm from the edge. same applies for the other compondtes already on the top edge make sure theres that 0.73cm clearance along that edge. move both switchs down to the bottom inbeween the esp32 and J1. also make the traces neat no lines going over ccomponets and also fix all the eroors theres cuts and deadends to the traces
I’ll adjust the placement as requested, then remove stale/cut/dead-end traces caused by moving parts and rerun routing/review. I’ll keep J2 and the top-edge parts about 7.3 mm from the top edge, and move RST_SW/BOOT_SW down between the ESP32 and J1.
I’m out of execution credits, so I had to stop after the placement step.
Completed:
  • Moved J2 to the top-left edge area with about 7.3 mm clearance from the board edge.
  • Adjusted the other top-edge components so they keep that same top-edge clearance.
  • Moved RST_SW and BOOT_SW down between the ESP32-S3 module and USB-C connector J1.
  • Preserved the ESP32 antenna orientation facing the bottom edge.
  • Placement now has no overlap or out-of-bounds issues.
Still to do:
  • Delete stale/dead-end traces created by moving components.
  • Re-route the affected nets.
  • Clean up trace paths so they don’t run awkwardly over/through component areas.
  • Rerun review and fix the remaining routing errors, including the USB D+/D− airwires.
