I can’t execute the PCB setup because no ACUs are currently available.

Completed so far: the schematic architecture, component selection, wiring, and supporting firmware/bring-up/compliance documents. Remaining: define the board outline and stackup, place the SiWG917 at a board edge with its antenna keepout, isolate the SHT41 from heat sources and airflow obstructions, cluster the USB-C/eFuse/buck power path, then run overlap and placement DRC checks.

I can’t analyze or run auto-layout because no ACUs are currently available, so no PCB changes were applied.

Remaining work: inspect the board outline, stackup, existing placement, airwires, and DRC; then run component placement and/or routing as needed, preserving the SiWG917 antenna keepout and thermal isolation around the SHT41.

I can’t run PCB analysis or auto-layout because the account has no available ACUs. No new board changes were applied.

Current state: the schematic is complete, but PCB setup, RF/thermal-aware placement, routing, and final DRC verification remain. Once ACUs are available, the next pass should inspect the existing board state, place components if necessary, route remaining airwires, and automatically apply the validated result.
