This repository includes the different symbol and footprint libraries used to create devices at LambdaKB.dev as well as our KiCad project templates.
This repository is provided AS IS, without any warranty. Use at your own risk. We do not assume any responsibility for damages or broken PCBs due to the use of the libraries present in this repository and any potential errors in it.
We try to keep every library as up-to-date and accurate as possible, but we cannot guarantee that it is always correct. If you find any errors in this library, please open an issue or pull-request. We will try to fix them as soon as possible.

To ensure consistency and maintain quality, follow these best practices when adding or modifying components:
- Symbols and footprints must be in the official KiCad format (v6+ recommended).
- All names (library items, fields, files) and descriptions must be in English.
- Component outlines should be drawn on the appropriate Fabrication layer (
F.FaborB.Fab) with accurate dimensions. - Silkscreen around a component should be spaced at least 0.1 mm from the component's outline on the
F.Fab/B.Fablayer. - If a variant of a component is needed, it should be named
<component_name>_<variant_suffix>, where the suffix describes the variant (e.g.,nSilkfor no silkscreen,sqSilkfor square silkscreen). - Use
REF**as the default reference designator in symbols. - Validate symbols and footprints with KiCad's built-in tools before adding them.
