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.

I’ll read the attached instructions and apply them to the current project if they’re actionable, without recreating the schematic unless explicitly required.

Blocked: your account currently has no available ACUs, so I can’t continue executing PCB edits or checks.

Accomplished this session:

Read the new attachment and confirmed it is a continuation/polish request for the existing project.
Re-ran board/routing checks.
Identified the remaining ESP32 warning as two unnamed ESP32 footprint mount/dummy pads overlapping the real GND pad.
Attempted a non-destructive fix by disabling those duplicate dummy pads, but the latest inspection still showed them active, so the issue remains unresolved.

Remaining work:

Remove or correctly neutralize the two duplicate ESP32 dummy pads causing the GND/mount overlap.
Re-run DRC and routing precheck.
Continue verified low-voltage routing only, while keeping BATTERY_POWER_MATRIX_CONCEPT_ONLY conceptual.
Update PCB Final Review Notes, Draft BOM, and Schematic Review Notes after final checks.

3D View

Schematic is Auto-placed

The schematic has been arranged automatically. Flux can redraw it to be more readable, with components placed in related groups and wires drawn more legibly. This takes about 10-60 mins.

Draft BOM - Concept Model

Project: Universal Configurable 10-Battery Controller – Concept Model Date: 2026-07-13

This draft BOM is for presentation/concept review only. Generic parts and placeholder footprints remain intentional.

BOM Notes

This BOM is not procurement-ready.
Placeholder components are intentionally used for concept visualization.
BSS138 devices are visual MOSFET placeholders only and are not rated for a real 10-battery switching matrix.
Final high-current switching, battery protection, charging, and safety components must be selected from verified electrical requirements before manufacturing.
