KiCad is an open source electronic design automation (EDA) software suite used to create printed circuit boards (PCBs). It is a free, cross-platform application that runs on Windows, Mac OS X, and Linux operating systems. KiCad includes a complete set of tools for designing and laying out a PCB, including schematic capture, PCB layout, library editing, and SPICE simulation. KiCad also offers a comprehensive library of parts with footprints, 3D models, and associated BOMs. KiCad is designed to be user-friendly, providing users with a graphical interface to create, edit, and save their PCB designs. It also provides a wide range of features for users to create custom parts, simulate circuits, and generate output files for manufacturing.
