Using Knowledge Base Tool.

Assembling the plan.

I’ll add a 5V SSD1306 I2C header and two ULN2003A input headers, with DNP 4.7k pull-ups, wired per your pin choices.
  • SSD1306 4-pin header [GND, VCC, SCL, SDA] → GND, 5V, A5, A4.
  • Two 4.7k Resistors as DNP pull-ups: A4→ 5V, A5→ 5V.
  • ULN2003A header 1 (IN1,IN2,IN3,IN4,VCC,GND): IN1..IN4 → D4–D7; VCC→ 5V, GND→GND.
  • ULN2003A header 2 (IN1,IN2,IN3,IN4,VCC,GND): IN1..IN4 → D8–D11; VCC→ 5V, GND→GND.
Click Start on the plan bar and I’ll execute these changes.

  • 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.
