Using Knowledge Base Tool.

Checking if I can make the changes for you.

I’ve prepared a plan to complete the schematic wiring, test pads, labels, and ERC per your approvals. It’s ready to execute.

What I will do:

Power rails: connect battery, charger, regulator, and 3V3 decoupling.
Motors: add 100 Ω gates, 100 kΩ pulldowns; wire drains/sources and VBAT.
Interfaces: I2C with 4.7 kΩ pull-ups; UART with auto-boot caps.
Indicators: LED sink path; buzzer via NPN on 3.3V.
Assign J12–J17 and label nets; run ERC.

Click Start on the plan bar to run it.

Plan

Goal: complete wiring for power, motors, I2C, UART, LED, buzzer, test pads, and run ERC per your mappings.

Plan ready. I’ll:

Connect power rails between J11, U7, J10, U9.
Wire motors Q1–Q4 with 100 Ω/100 kΩ networks to U1 and motor connectors U2–U5.
Hook up I2C U6 and UART U8 with auto-boot caps C10, C11, LED D1, buzzer BUZZER1/Q5.
Assign J12–J17 and add labels; run ERC.

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.
