USB-C 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.

I can’t execute project changes right now because this account has no available ACUs, so AI design actions are unavailable.
Current project state:
  • New empty project: Great Pink Lightcycle
  • Components: 0
  • Nets: 0
  • No schematic or PCB work has been performed yet in this session.
What remains to be done once ACUs are available:
  • Create a project specification for the USB-C Wi-Fi/BLE temperature/humidity sensor node.
  • Select parts: low-power Wi-Fi/BLE MCU/module, digital T/RH sensor, USB-C receptacle, 5 V protection/power-path parts, regulators, programming/debug interface, and passives.
  • Build the schematic with USB-C 5 V default power, reverse/OVP/UVLO/OCP protection, 0.5–3 A source planning, MCU, sensor, decoupling, boot/programming, and RF layout constraints.
  • Verify ERC/power budget, then proceed to PCB placement/routing with antenna keepout and USB-C layout rules.
