PCB Layout Design Guidance

Autopilot
Here’s the progress against your plan:
Work completed
- Project description and system architecture defined
- All major ICs and active components added to the schematic (STM32G070CBT6, BMP581, AP2112K-3.3, BQ24075, USB-C, LCD FPC, LEDs, resistors, capacitors)
- Nets connected per locked Phase-2 netlist
- Schematic reviewed; passive voltage/power ratings set; VCAP and CHG pull-ups added
- Footprints assigned; generic passives set to 0603
- Board size set to 30 mm × 20 mm; bottom layer configured as solid GND plane
- Four NPTH mounting holes placed at (±13, ±8)
- Paused after placement of mounting holes for your review of board size and mounting placement
Tasks not done / cannot automate
- Stackup configuration (2-layer FR4 1.6 mm)
- Net-class assignments and design rule width/clearance settings
- Precise placement of USB-C, LCD FPC, charger, decoupling cluster, MCU and other components
- PCB routing of power, control and signal nets
- DRC/ERC cleanup
- Gerber/Drill file/BOM/PnP/pin-map generation and packaging
Success criteria
Not yet met—the schematic is complete, but PCB layout, DRC clean-up, and fabrication outputs remain to be done.
Recommended next step
Configure the PCB stackup and layout rules (net classes, trace widths, clearances), then place the remaining components and route the board. Once routed and DRC-clean, I can generate the fabrication outputs and bundle them into SMD_V2_FAB_v1.zip.

- 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.
