🏷️ Naming Conventions

Symbols (.kicad_sym files)

• Format: [Category]_[Manufacturer]_[Series].kicad_sym
• Examples:

  • Logic_TI_74HC.kicad_sym

  • Power_LTC_Switching.kicad_sym

  • Connectors_JST_XH.kicad_sym

  • Logos_Personal.kicad_sym

Individual Symbol Names (within .kicad_sym)

• Format: [Partnumber]_[Package]_[Variant]
• Examples:
  • TPS54340_HTSSOP-14_PowerPAD
  • STM32F407VGT6_LQFP-100
  • USB-C_16Pin_Receptacle
  • Logo_MyCompany_10mm

Footprints (.pretty folders)

Note: Standard passives and common ICs use existing KiCad footprints!

• Format: [Category]_[Specification].pretty
• Examples:
  • QFN_Custom.pretty
  • USB_Connectors.pretty
  • Logos_Silkscreen.pretty
  • Mechanical_Standoffs.pretty

⚙️ Best Practices

Component Strategy

1. Use KiCad footprints: Don't reinvent the wheel for standard packages
2. Consistent naming: Follow established naming conventions
3. Documentation: Include manufacturer data and datasheets
4. Quality: Test all components before adding to library

Workflow

Adding New Component

1. Check KiCad: Verify symbol/footprint don't exist in standard libraries
2. Research: Find datasheet and manufacturer information
3. Create symbol: With complete manufacturer data
4. Link footprint: Use existing KiCad footprint or create custom
5. Test: Use in test circuit
6. Document: Add to documentation
