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.

I can’t start building the design right now because this account has no available ACUs, so AI execution features are unavailable.
Current project state:
  • New empty project: Statutory Black Proton Packs
  • Components: 0
  • Nets: 0
  • No schematic, PCB, or documentation has been created yet.
What remains to be done once ACUs are available:
  • Define the architecture for a USB-C powered Wi-Fi/BLE temperature and humidity sensor node.
  • Select parts: ultra-low-power Wi-Fi/BLE MCU/module, digital T/RH sensor, USB-C receptacle, input protection/load switch/eFuse, 5 V to 3.3 V regulator, ESD/TVS, passives, programming/debug interface.
  • Create the schematic with USB-C 5 V default power input, CC resistors, reverse/OVP/UVLO/OCP protection, 0.5–3 A source planning, 3.3 V rail, MCU, sensor, and support circuitry.
  • Add consumer-use design notes: RF antenna keepout, safety/protection assumptions, bring-up plan, and regulatory considerations for Wi-Fi/BLE.
  • Proceed to PCB layout with RF-aware placement and routing after schematic review.
