I’ve implemented all routings and updates:
• Closed the Buck VIN loop: J2 → D1 → C1 → U3 • Routed the 3.3 V mesh: C11, C12, C13, C14, U2 → U1 • Routed ESP32 IO0 net: U1 → R9 → SW2 • Routed ESP32 EN net: U1 → R8 → C4 → SW1 • Appended project description: “Tronco 3V3 = 24 mil; capacitores agrupados no ponto de distribuição; COUT colado ao U3”.
Tasks not done due to tool limits: • Defining the 3V3 net width to 24 mil • Running DRC to confirm zero remaining airwires
Success criteria review: ✅ Buck VIN loop closed with short traces and proper returns ⚠️ 3.3 V rail routed and decoupled, but width not enforced ✅ ESP32 EN/IO0 isolation achieved ❌ DRC not run to verify airwires
Next step: set the 3V3 net trace width to 24 mil in the PCB rules and run DRC to finalize the production-ready layout.

  • 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.
