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 USB‑C (5 V) Wi‑Fi/BLE environmental T/RH node. Here’s the plan:
  1. Add core components: dual‑radio Wi‑Fi/BLE MCU, digital T/RH sensor, USB‑C Receptacle, antenna placeholder.
  2. Power input: USB‑C sink CC terminations, reverse/OVP/UVLO/OCP (eFuse/ideal‑diode), 5 V→3.3 V buck, ESD on VBUS/CC.
  3. Support passives: decoupling; I2C pull‑ups 4.7k Resistor respecting 400 pF bus limit.
  4. Connect nets: power rails, I2C, required boot/program pins; set properties.
  5. Layout prep: RF antenna keepout/ground clearance; place decoupling at pins; run ERC/DRC and availability checks.
