Align component groups, repair affected routing, and add preservation
audits.
Assign the confirmed U2 footprint and update pull-ups to 2 kΩ across
design files.
Document user acceptance, switch to an A3 worksheet, and refresh PCB
exports.
Introduce an editable KiCad 10 schematic and routed two-layer 82 × 80 mm
layout with local provisional footprints, validation tooling, and
component
research. Keep the RS-232 male-module mapping and mechanical clearances
explicitly provisional pending hardware verification.
