Temperature and Humidity 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.

I can’t start modifying the project because this account currently has no available ACUs, so AI execution features are unavailable right now.
Current project state:
  • New empty project: Brave Cyan Wall-E
  • Components: 0
  • Nets: 0
  • No schematic, PCB, or project documentation has been created yet.
What remains to be done when ACUs are available:
  • Create a project specification for the USB-C powered Wi-Fi/BLE temperature-humidity node.
  • Select parts: dual-radio low-power MCU/module, digital T/RH sensor, USB-C receptacle, 5 V input protection, OVP/UVLO/OCP/load switch or eFuse, and 3.3 V regulator.
  • Build and verify the schematic.
  • Add firmware pin map, bring-up plan, and consumer-use regulatory notes.
  • Proceed to PCB placement/routing with RF antenna keepout and USB-C/power-path layout constraints.
