Temperature and Humidity Sensor 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’ll create your low-power Wi‑Fi/BLE temperature & humidity node with USB‑C 5 V input and full protection. Here’s the plan:
  1. Add key ICs: dual‑radio MCU (Wi‑Fi 2.4 GHz 802.11 b/g/n + BLE 5.x), digital T/RH sensor, USB‑C receptacle + CC resistors.
  2. Power path: reverse/OVP/UVLO/OCP at USB‑C input; 5 V → 3.3 V regulator; decoupling.
  3. Supporting: antenna/matching, programming header, status LED, pull‑ups, test points.
  4. Net connections across subsystems; prep footprints; run ERC/DRC.
Click Start on the plan bar to proceed, or tell me part preferences (e.g., ESP32‑C3/C6/S3 variant, sensor model, buck vs LDO) and I’ll update before running.
