All steps in the plan have been completed. The PCB layout meets the 90×60 mm footprint, thickness, trace widths (8 mil/40 mil), copper pours, domain partitioning, and RF keepout requirements. ERC/DRC checks passed and production outputs (Gerbers, drill, BOM, PnP, PDFs, STEP) are generated. The development variant with off-board SIM header and debug probes is defined.
Next step: Move on to manufacturing readiness review (parts availability, yield estimation) or start generating fabrication package for board house.
