Diseño de PCB para Controlador LED RGBW

Thought for 2 sec

Puedo ayudarte a diseñar el PCB, pero no puedo ejecutar cambios en el proyecto en este momento porque se agotaron los créditos de ejecución.

Estado actual del proyecto:

Nombre: Simulación de Circuitos tabla 2
Componentes actuales: 1 inductor genérico
Redes eléctricas: 0
No se ha creado todavía el circuito del controlador RGBW.

Diseño recomendado para tu LED RGBW de 18 W a 12 V controlado por WiFi con ESP32:

Bloques principales del PCB

Entrada de alimentación 12 V
- Conector de entrada DC 12 V
- Fusible o polyfuse
- Protección contra inversión de polaridad
- Diodo TVS para picos de voltaje
- Capacitor electrolítico de entrada
Regulador 12 V a 3.3 V
- Convertidor buck, no LDO, porque el ESP32 consume picos altos y un LDO desde 12 V disiparía demasiado calor.
- Salida de 3.3 V para alimentar el ESP32.
- Capacitores de entrada/salida según datasheet del regulador.
Módulo ESP32
- Recomendado: ESP32-WROOM-32E o similar.
- Alimentación a 3.3 V.
- Capacitores de desacoplo cerca del módulo.
- Botones EN/BOOT opcionales para programación.
- Header UART para programar: 3V3, GND, TX, RX, EN, IO0.
Etapa de potencia para LED RGBW
- 4 canales independientes:
  - R
  - G
  - B
  - W
- Cada canal con MOSFET canal N lógico en configuración low-side.
- El ESP32 controla las compuertas con PWM.
- Resistencias en gate: 47 Ω a 220 Ω.
- Pull-down en gate: 100 kΩ.
- MOSFETs recomendados de baja Rds(on) con Vgs = 3.3 V.
Conector hacia LED RGBW
- Terminal común: +12 V
- Salidas conmutadas:
  - LED_R-
  - LED_G-
  - LED_B-
  - LED_W-

Corriente estimada

LED total:
18 W / 12 V = 1.5 A total

Si se reparte en 4 canales:

Aproximadamente 0.375 A por canal
Recomiendo dimensionar cada canal para al menos 1 A
Entrada 12 V recomendada: mínimo 2 A, mejor 3 A para margen.

Componentes sugeridos

1 × ESP32-WROOM-32E
1 × Buck 12 V a 3.3 V, mínimo 600 mA, ideal 1 A
4 × MOSFET canal N lógico, mínimo 30 V, ≥2 A, baja Rds(on) a Vgs = 2.5/3.3 V
4 × resistencias gate 100 Ω
4 × resistencias pull-down 100 kΩ
1 × conector DC 12 V
1 × conector LED RGBW de 5 pines
1 × TVS para línea de 12 V
1 × fusible/polyfuse 2 A a 3 A
Capacitores:
- 100 µF o más en entrada 12 V
- 10 µF cerca del buck
- 10 µF + 100 nF en salida 3.3 V
- 100 nF cerca del ESP32

Pendiente por hacer cuando haya ejecución disponible

Crear el esquemático completo.
Seleccionar componentes reales con huella PCB.
Consultar datasheets del ESP32, regulador buck y MOSFETs.
Cablear:
- Alimentación 12 V
- Regulador 3.3 V
- ESP32
- 4 canales MOSFET PWM
- Conectores
- Protecciones
Ejecutar revisión ERC.
Corregir errores.
Pasar a layout PCB.
Colocar componentes.
Rutear pistas, usando pistas más anchas para 12 V y canales LED.
Ejecutar revisión DRC.
Generar archivos de fabricación.

Para este diseño usaría una placa de 2 capas, con plano de GND, pistas de potencia dimensionadas para al menos 1.5–3 A en la entrada y pistas separadas para cada canal RGBW.
