KiCad

KiCad is an open-source EDA (Electronic Design Automation) suite that supports schematic capture and PCB layout. It caters to hobbyists, small businesses, and professionals seeking a free, extensible platform. Users can create multi-sheet schematics, define netlists, and design multi-layer boards. A built-in 3D viewer renders boards with footprints and mechanical outlines. KiCad’s robust library editor handles custom symbols and footprints. The active community develops plugins, footprints, and translation packs. As a zero-cost solution with frequent updates, KiCad is highly regarded for electronics design and learning.
