Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
Debe ser un nodo ambiental de bajo consumo con un sensor digital de temperatura/humedad relativa y un microcontrolador de ultrabajo consumo. with Wi-Fi + Bluetooth (doble radio) — 2,4 GHz 802.11 b/g/n más BLE 5.x powered by USB-C (5 V) — Conector USB-C de 5 V por defecto; incluye protección contra polaridad inversa/sobretensión/subtensión/sobrecorriente y está diseñado para fuentes de 0,5 a 3 A..

No he podido empezar a modificar el proyecto porque la cuenta no tiene ACUs disponibles, así que las funciones AI de diseño/ejecución están bloqueadas ahora mismo.
Estado actual del proyecto:
  • Proyecto recién creado, sin componentes ni nets.
  • No se ha añadido todavía el nodo ambiental.
  • Requisitos capturados: sensor digital de temperatura/humedad, MCU ultrabajo consumo con Wi‑Fi 2.4 GHz 802.11 b/g/n + BLE 5.x, alimentación USB‑C 5 V, protección contra polaridad inversa, sobretensión, subtensión y sobrecorriente, para fuentes de 0.5–3 A y uso consumidor.
Pendiente cuando haya ACUs:
  1. Seleccionar MCU/módulo Wi‑Fi + BLE de bajo consumo, probablemente ESP32‑C3/C6/S3 según prioridades.
  2. Seleccionar sensor T/RH digital, por ejemplo Sensirion SHT4x/SHT3x o TI HDC302x.
  3. Diseñar entrada USB‑C 5 V con CC resistors, protección ESD, fusible/eFuse o power switch, OVP/UVLO y protección de inversión.
  4. Añadir regulación 3.3 V eficiente para MCU + sensor.
  5. Crear esquema, validar ERC, preparar layout con keepout de antena y documentación de bring-up/compliance.
