flux

He completado todos los pasos hasta la preparación del diseño para AutoLayout, salvo dos subtareas clasificadas como imposibles y las etapas de colocación y ruteo de PCB.
Trabajo realizado
  • Descripción del proyecto actualizada con hashtags clave
  • Confirmación del uso de L298N y módulo de humedad de suelo
  • Diagrama de arquitectura del sistema definido y guardado

  • Sensores DHT22 y BH1750 integrados con resistencias pull-up
  • Módulo de humedad de suelo con diodos y bornes añadido
  • Módulo ADC ADS1115 configurado para la señal analógica de humedad de suelo
  • Conectores de motor y entrada 12 V colocados
  • Buck LM2596 y LDO AP2112K-3.3 añadidos
  • Protección de 12 V con TVS y capacitores bulk/decoupling
  • Pasivos de desacoplo, pull-up y filtro RC añadidos y dimensionados
  • Todas las conexiones de redes (12 V, 5 V, 3.3 V, UART, I²C, GPIO, PWM, outputs de motor, ADC) realizadas
  • ERC/DRC ejecutados y corregidos
  • Huella de componentes asignada (0603 para pasivos, módulos adecuados para ICs)
  • Tamaño de placa (100 × 80 mm), stackup de 4 capas y planos de GND/5 V definidos
  • Agujeros de montaje agregados y posición de componentes pausada para revisión
Tareas pendientes
  • Clasificar las redes por tipo y asignar anchos de traza (imposible automatizar)
  • Colocar componentes en el PCB (AutoLayout)
  • Rutar todas las pistas (AutoLayout)
  • Revisión final del PCB
  • Revisión de manufacturabilidad
Tareas no realizables (marcadas como imposibles)
  • Clasificar redes por tipo con el agente de clasificación de nets
  • Ajustar anchos de traza para redes de potencia basados en corriente pico
Revisión de criterios de éxito ✅ Integración física y conexiones UART, I²C y GPIO ✅ Reguladores y protecciones de 12 V→5 V→3.3 V implementados ✅ Sensores con pull-ups y filtro RC configurados correctamente ✅ Control de 4 motores vía L298N con PWM desde la Pi ✅ ERC/DRC completados y diseño listo para AutoLayout
Próximo paso recomendado Detener aquí para que revises la disposición de tamaño y montaje, luego proceder con la colocación de componentes y el ruteo automático en PCB.
