USB-C Wi-Fi/Bluetooth Sensor Node
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 can’t execute design changes right now because this account has no available ACUs, so AI project mutation tools are unavailable. No schematic, components, nets, or documents have been added yet; the project is still empty with its placeholder name.
What remains to be done once ACUs are available:
- Rename the project and create a requirements/spec document for the USB-C powered Wi-Fi/BLE T/RH sensor node.
- Select the MCU/module, likely a certified ESP32-class Wi-Fi + BLE 5.x module for consumer compliance.
- Select a digital temperature/RH sensor, USB-C receptacle, protection IC/eFuse/load switch with reverse/OVP/UVLO/OCP, 3.3 V regulator, ESD protection, and passives.
- Build and verify the schematic: USB-C 5 V default CC resistors, 0.5–3 A source planning, protected 5 V rail, 3.3 V rail, MCU boot/programming support, I2C sensor, decoupling, and RF antenna keepout requirements.
- Prepare layout constraints for USB-C, protection path, regulator, sensor placement/thermal isolation, and RF keepout, then route and run DRC/ERC.
