Launch KiCad and then click the “Symbol library editor” icon. Select “Manage Symbol Libraries” from the Preferences menu.


There are several different ways to manage third party libraries like this one. Using git clone is a great way to keep it up to date.
Kicad No Component Libraries Are Loaded Using
How you decide to manage the library(s) within KiCad is open to debate, but the way I prefer to use them is to pull them in to the Project Libraries, that way they are managed separately from the default libraries, this can be done as such:
- Open KiCAD and create a new project. Open the project schematic file. Select the Preferences Component Libraries menu. Click the Add button to add a new library. Browse to select the symbols.lib file from your Ultra Librarian download. You have now added the new library and are ready to place the component on your KiCAD schematic.
- Run Pcbnew via KiCad manager. Modify and update the Pcbnew configuration, especially the footprint library list. Pcbnew will create or update a library list file called footprint library table.There are 2 library list files (named fp-lib-table): The first (located in the user home directory) is global for all projects and the second (located in the project directory) is optional and specific.
