There are two methods to import components:
Best for batch imports or when you know the LCSC part number.
Use the alias (already configured in .zshrc):
This downloads the symbol, footprint, and 3D model to the centralized libs/ folder.
Best for browsing and importing directly within KiCad.
1. In KiCad, go to Plugin and Content Manager 2. Search for "EasyEDA" or "LCSC" 3. Install the plugin
