Schematic wiring and the core project files are in place, including the spec, power budget, firmware starter, bring-up plan, and FCC/CE planning notes.
Worked for 1 min 56 sec
Built the schematic for a USB-C powered Wi‑Fi/BLE temperature + humidity sensor node using ESP32‑C3‑MINI‑1‑N4, SHT40, TPS25940 eFuse protection, MP28301 3.3 V buck regulation, USB-C CC pull-downs, USB data ESD, VBUS TVS, reset/boot controls, status LED, and test pads. I also created the key project files: Project Specification, Power Budget and Design Notes, Firmware Starter, Board Bring-Up Plan, and Technical Construction File.
Open items:
- I’m blocked from continuing because your account currently has no available ACUs, so AI tools are unavailable.
- Full check results show expected PCB airwires because layout/routing has not been done yet.
- Several generic passives/testpoints still need final manufacturer part numbers before manufacturing export.
- Layout still needs antenna keepout, SHT40 thermal isolation, USB-C ESD placement, and buck-regulator power-loop placement.
Suggested next steps:
- Refill/enable ACUs, then ask me to finish verification and clean remaining manufacturing metadata.
- Proceed to PCB placement with ESP32 antenna edge keepout and isolated SHT40 placement.
- Route the board, then run DRC/ERC again.
- Lock exact passive/inductor MPNs and generate manufacturing files.
