Configure PCB dimensions, layers, and plane assignments
Set net classes and trace widths
Place components by functional block
Route all nets and refine critical routes
Run DRC and clear violations
Success criteria: Not yet met—all schematic blocks, PCB placement, routing, and ERC/DRC checks remain to be completed.
Next step: Generate and save the system-architecture Mermaid diagram showing the VBAT path, Buck→LDO, Dual BLDC, Dual Brushed, I²C/MotorFlex, Test Pads, and MCU/Core blocks, then update the “System Architecture” property.
