ESP32-S3 Firmware Refinement

flux

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.
