Rebuild: fix J1 orientation (90°), re-place all components, Freerouting orthogonal routing, 84 GND vias
- J1 rotated 90° so USB-C mating face faces left board edge
- All 23 components re-placed with proper spacing (8 courtyard overlaps remain — all ESP32 keepout)
- Freerouting v2.2.4: 21/25 nets autorouted cleanly
- 3V3/VBUS_SENSE manually routed on B.Cu for remaining 4 nets
- 84 GND stitching vias (grid + around_refs)
- DRC: 158 violations (0 tracks_crossing, 2 shorts, 84 via_dangling zone-fill dependent)
- Board 65x35mm, 2-layer

USB-C PD board with ESP32-S3
Complete initial design:
- CH224K PD sink controller (custom corrected symbol)
- USB-C receptacle (16-pin USB2.0)
- P-Channel MOSFET VBUS switch
- LD1117S33 3.3V LDO regulator (800mA)
- ESP32-S3-WROOM-1 module
- 15 nets: VBUS, VOUT, 3V3, GATE, CC1/CC2, USB_DP/USB_DN
- 5.1kΩ CC pull-down resistors
- CFG1/CFG2 for PD voltage selection
- Input/output decoupling capacitors
