1. Open kicad/surftrakcarrier.kicadsch 2. Tools → Update Symbols from Library (resolves Device:R, ConnectorGeneric:, etc.) 3. Wire up pins in the schematic GUI — all global net labels are already placed; connect each component's pin stubs to the matching label. Use docs/SCHEMATICDESIGN.md as the pin-by-pin reference. 4. Run ERC (Inspect → Electrical Rules Checker), fix all errors 5. Open…
