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.

You want a consumer USB-C powered temperature/humidity sensor node with Wi-Fi + Bluetooth.
I’ve built the plan and it’s ready to execute. The work will:
  1. Define the protected USB-C 5 V -> regulated 3.3 V architecture
  2. Add the main sensing, wireless, and protection blocks
  3. Wire the full schematic and review it for completeness
  4. Set up the PCB for placement and routing

Add ESD protection
Use ESP32-C3
Specify regulator target
