The KiCad symbol libraries are the individual .lib files, with the corresponding .dcm files containing symbol metadata. These symbols are best used in combination with the official footprint libs.


The files packaged here are intended for KiCad version 5 or nightly builds that support the schematic library version 2.4 or newer.

Updating via Git

Users who wish to keep symbol libraries up to date can track the GitHub repository.
