# /kicad/libraries/symbols

Custom schematic symbols for your KiCad project.

## File Format
- Store symbols as `.kicad_sym` files
- Each file can contain multiple related symbols

## Naming Convention
- Use descriptive names: `ProjectName_ComponentType.kicad_sym`
- Examples:
  - `MyProject_MCU.kicad_sym`
  - `MyProject_Connectors.kicad_sym`
  - `MyProject_PowerManagement.kicad_sym`

## Symbol Creation Guidelines
- Include all necessary pins with proper electrical types
- Add symbol properties (Reference, Value, Footprint, Datasheet)
- Use standard KiCad symbol conventions
- Include documentation strings
- Set appropriate pin numbers and names

## Adding to Project
1. Open KiCad Project Manager
2. Go to **Preferences → Manage Symbol Libraries**
3. Click **Add** and browse to this directory
4. Select your `.kicad_sym` file
5. Set library nickname and path (use relative paths)
