USB-C WiFi BLE Sensor Design
Thought for 50 sec
I’m blocked because the account has no available ACUs, so I can’t continue AI tool work right now.
Completed so far:
- Renamed the project to USB-C WiFi BLE Sensor Node.
- Updated the project description.
- Created the initial Project Specification file.
- Confirmed the schematic started empty.
- Sourced and added the main components:
- ESP32-S3-MINI-1-N8 Wi‑Fi/BLE module
- SHT40 temperature/humidity sensor
- USB-C receptacle
- USB input protection/current-limit IC
- USB-C port protection IC
- 3.3 V buck regulator
- USB D+/D− ESD protection
- BOOT and RESET buttons
- Status LED
- 5 V, 3.3 V, and GND test points
Still remaining:
- Add support passives: decoupling capacitors, I2C pull-ups, USB-C CC pull-downs, regulator feedback/boot/input/output components, LED resistor, boot/reset RC parts.
- Query datasheets for every active IC before wiring.
- Wire the USB-C input, protected 5 V path, 3.3 V regulator, ESP32, SHT40, USB data, buttons, LED, and test points.
- Run schematic checks and fix ERC issues.
- Create firmware, board bring-up, and regulatory documentation.
- After schematic validation, ask for approval before moving to PCB layout.
