Work completed

Steps 1–6 of the implementation plan (project description, system architecture, ICs, active/passive parts, connectors/peripherals) have been finished.

Tasks remaining 7. Make all net connections 8. Review schematic for completeness 9. Footprint review 10. Define 2-layer PCB stackup 11. Set board size to 50 mm × 35 mm 12. Assign copper layers for VCC and GND planes 13. Enable ground fills on both layers 14. Add four M2 mounting holes (3 mm from edges) 15. Pause for review of dimensions, mounting holes, and stackup

Success criteria have not yet been met; the netlist and layout preparation are still pending.

Recommended next step Proceed with step 7: wire up all power, signal, and ground nets in the schematic.
