Netlist-first KiCad-import package for the single carrier PCB (ESP32-WROOM-32E, SINK/BROADCASTER assembly variants): - hardware/carrier/resound-carrier.net : KiCad s-expr netlist, 44 components / 40 nets, real library footprints (RF_Module:ESP32-WROOM-32, 2x13 stacking header, 0402 passives, SOT-23 auto-reset, JST-SH HUD conn). Parens balanced. - hardware/carrier/BOM.csv : 44 parts (ref/value/footprint/MPN/DNP/notes). - hardware/carrier/LAYOUT.md : 45x45 4-layer stackup, 15mm antenna keep-out, placement, JLCPCB DRC, SINK-vs-BROADCASTER variant + address-strap table. - hardware/carrier/README.md : KiCad import steps + caveats. Agent decisions flagged for EE: LED moved off the GPIO13 strap to LED_DAT=GPIO21 / LED_CLK=GPIO4; verify WROOM footprint pad numbering; UART2 is connector-only this rev. Deliverable is import-ready netlist+BOM+spec, not a finished .kicad_pcb. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
