KiCad is a free software suite for electronic design automation (EDA). It facilitates the design of schematics for electronic circuits and their conversion to PCB designs. KiCad was originally developed by Jean-Pierre Charras, and features an integrated environment for schematic capture and PCB layout design. Tools exist within the package to create a bill of materials, artwork, Gerber files, and 3D views of the PCB and its components.


The KiCad suite has five main parts:

  • kicad - the project manager.
  • eeschema - the schematic capture editor.
  • pcbnew - the PCB layout program. It also has 3D View.
  • gerbview - the Gerber (photoplotter documents) viewer.
  • Bitmap2Component - tool to convert images to footprints for PCB artwork.


KiCad uses an integrated environment for all of the stages of the design process: Schematic Capture, PCB layout, Gerber file generation/visualization and library editing.

KiCad is cross-platform program, written with wxWidgets to run on FreeBSD, Linux, Microsoft Windows and Mac OS X. Many component libraries are available, and users can add custom components. The custom components can be available on a per-project basis, or installed for use in any project. There are also tools to help with importing components from other EDA applications, for instance EAGLE. Configuration files are in well documented plain text, which helps with interfacing to CVS's or SVN, as well as with automated component generation scripts. Up to 32 copper layers are supported.

Multiple languages are supported, such as English, Catalan, Czech, German, Greek, Spanish, Finnish, French, Hungarian, Italian, Japanese, Korean, Dutch, Polish, Portuguese, Russian, Slovene, Swedish, and Chinese.

The 3D PCB viewing function is based on VRML models and the board model can be exported for CAD integration.

KiCad has a built-in autorouter for basic, single connections. Alternatively, the open source (but currently discontinued) java-based FreeRouting can be used. To do that, a PCB design is exported to a Specctra DSN file, which is then loaded into FreeRouting. After the autorouting is done, the result is saved as a Specctra session and imported back into KiCad's pcbnew module.

Since 2013, CERN has added important features for high speed PCB routing, like track length matching, differential pair support and a new Graphic Abstraction Layer based on OpenGL. CERN contributes to the development of KiCad through donations, which directly support a developer working on the application. Contributions may be made through the links on KiCad's website.

KiCad recently demonstrated the interactive router, which features the ability to walk around existing traces in the way, or shove existing traces into a different position while maintaining their connectivity.
