circuitrodev/cern-kicad-libs

This is a component library collection for KiCad, an open-source tool used to design printed circuit boards. KiCad uses "symbols" (schematic diagrams representing individual electronic components) and "footprints" (physical pad layouts placed on the board). This repository contains 8,365 symbols and 9,246 footprints drawn from the component library used internally at CERN, the European particle physics research organisation. The libraries were originally created and maintained by CERN's Electronics Design Office using Altium Designer, a different electronics design tool. They are automatically converted to KiCad format each night using a command-line conversion tool, making them available to engineers and designers who use KiCad rather than Altium. The libraries do not include 3D models or component datasheets, as that material is largely not owned by CERN. The libraries have been open-sourced so they can be used freely by designers outside CERN, including CERN contractors. This GitHub repository is a mirror of the upstream project hosted on GitLab, created for the convenience of users who primarily work within GitHub. It is not affiliated with or endorsed by CERN. The mirror also includes a searchable live web viewer with SVG previews of every symbol and footprint, usable without installing KiCad. The libraries are released under the CERN Open Hardware Licence v2 (permissive variant, CERN-OHL-P-2.0), which allows use in any project, open source or proprietary. The libraries are provided as-is with no dedicated support resources.
