KiCad

KiCad is an open-source software suite used for electronic design automation (EDA) that allows users to design schematics and printed circuit boards (PCBs). It provides a comprehensive environment for creating electronic designs, from schematic capture to PCB layout, and supports 3D modeling of boards.

KiCad offers tools for designing multi-layer PCBs, creating custom components, managing netlists, and performing design rule checks (DRC). It also includes a 3D viewer that helps visualize the physical layout of the board, making it easier to identify design issues before manufacturing. Its open-source nature makes it accessible for hobbyists, students, and professionals alike, offering a cost-effective alternative to commercial EDA tools while maintaining a robust feature set for complex designs.
