Completed the PCB presentation cleanup: preserved the schematic, reorganized the board into labelled functional zones, added mounting holes, section boxes, polarity labels, concept warnings, and routed selected verified low-voltage/control nets without forcing the battery matrix.
Open items:
- Remaining airwires are expected for the concept-only matrix and some unforced low-voltage items.
- A small ESP32 module GND/mount footprint overlap warning remains.
- I could not directly set/export saved 3D camera views from here.
Files created:
Suggested next steps:
- Open the 3D viewer and capture the requested presentation angles.
- Review the top PCB view for silkscreen readability.
- If this ever moves beyond presentation, redesign the high-current battery matrix from real electrical requirements.
