Wi-Fi and Bluetooth Sensor Node Design
Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
It should be a low-power environmental node with a digital T/RH sensor, ultra-low-power MCU with Wi-Fi + Bluetooth (dual-radio) — 2.4 GHz 802.11 b/g/n plus BLE 5.x powered by USB-C (5 V) — USB-C receptacle 5 V default; include reverse/OVP/UVLO/OCP protection and plan for 0.5–3 A sources.
Thought for 5 sec
I’m blocked from executing the design because this account currently has no available ACUs, so AI project-modification features are unavailable.
Current project state:
- New empty project created: Broken Scarlet Universal Remote
- No components, nets, schematic, PCB, or documentation have been added yet.
- Your requested design scope is clear: USB-C powered low-power Wi-Fi + BLE environmental node with digital temperature/RH sensing and protected 5 V input path rated for 0.5–3 A sources.
Remaining work once ACUs are available:
- Select MCU/module: likely ESP32-C6/C3/S3-class Wi-Fi + BLE 5.x module depending on power and certification goals.
- Select digital T/RH sensor, USB-C receptacle, protection ICs, regulator, and passives.
- Create schematic with USB-C 5 V default sink, CC resistors, reverse/OVP/UVLO/OCP protection, 3.3 V regulation, MCU, sensor, programming/debug, and test points.
- Add consumer-use documentation: power budget, bring-up plan, firmware pin map, and regulatory notes.
- Proceed to PCB placement/routing with RF keepout and USB-C/power protection layout constraints.
