KiCad

KiCad is an electronics design automation suite for drawing schematics and laying out printed circuit boards. It runs as a desktop application on Windows, macOS, and Linux and covers the full board design workflow, from schematic capture through PCB layout to inspecting the finished board in 3D.

The suite bundles a project manager, schematic editor, PCB editor, Gerber viewer, and 3D viewer, alongside CvPCB for footprint assignment, a page layout editor, and a bitmap-to-PCB-artwork converter. Shared geometry and file-handling libraries and utilities such as IDF and STEP converters support the editors.

KiCad is free software under the GPL, with localized interfaces maintained for most languages through community translation.
