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 build a low‑power Wi‑Fi/BLE environmental node on USB‑C (5 V) with robust protection.
  1. Add MCU module, T/RH sensor, USB‑C receptacle, eFuse, 5 V→3.3 V buck, ESD/TVS.
  2. Add CC Rd, I2C pull‑ups, decoupling/bulk caps, straps, LEDs.
  3. Wire USB‑C VBUS→eFuse→buck→3V3; CC; I2C; LEDs; boots.
  4. Place with antenna keep‑out, sensor exposure; route; pours.
  5. Run ERC/DRC and availability review.
Baseline parts: ESP32-C6-MINI-1, SHT45-AD1B-R3, USB Type-C Receptacle, TPS2595, TPS62160.
