Architecture¶

PinViz architecture overview.

Design Patterns¶

1. Separation of concerns: Model → Layout → Rendering pipeline
2. Factory pattern: Boards and devices use factory functions
3. Schema-first validation: Pydantic schemas validate config before runtime objects are built

Core Modules¶

• model.py - Core data structures
• boards.py - Board templates
• devices/ - Device registry, loader, and template catalog
• config_loader.py - Configuration parsing
• layout/ - Layout engine and routing components
• render_svg.py - SVG rendering
• cli/ - Command-line interface commands and output utilities
