Trabajo realizado
  • Eliminé el sensor U2 (MAX30102) de la PCB Principal.
  • Configuré los condensadores C1, C2, C3 y C4 como 100 nF de desacople.
  • Añadí un condensador de 10 µF para desacople de potencia (C5).
Tareas pendientes
  • Añadir conector FFC 4 pines (pitch 0.5 mm, contactos abajo) como J2.
  • Configurar R1 y R2 como pull-ups de 4.7 kΩ cerca de U1.
  • Cablear los nets en la PCB Principal (3V3, GND, SDA, SCL) entre J2, U1 y U4.
  • Renombrar nets a 3V3, GND, SDA y SCL.
  • Añadir propiedad de proyecto “keep_out_region” = “under ESP32 antenna”.
  • Esquemático Sensor: incluir U2, su desacople (C5), el conector FFC y cableado I²C.
  • Realizar ERC/DRC en ambos esquemas y layouts.
Revisión de criterios de éxito
  • ✅ MAX30102 eliminado de la PCB Principal.
  • ✅ Pasivos consolidados a 100 nF y 10 µF.
  • ❌ Pull-ups, conexión I²C completa y keep-out pendientes.
  • ❌ ERC/DRC aún no verificado.
Próximo paso recomendado Configurar los pull-ups de 4.7 kΩ y finalizar el cableado I²C (nets y renombrado) en la PCB Principal para luego proceder a revisión ERC/DRC.

  • Generic Capacitor
    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
