KiCad EDA v9.0.6 KiCad EDA v9.0.6 A Cross Platform and Open Source Electronics Design Automation Suite Schematic Capture KiCad's Schematic Editor supports everything from the most basic schematic to a complex hierarchical design with hundreds of sheets. Create your own custom symbols or use some of the thousands found in the official KiCad library. Verify your design with integrated SPICE simulator and electrical rules checker. PCB Layout KiCad's PCB Editor is approachable enough to make your first PCB design easy, and powerful enough for complex modern designs. A powerful interactive router and improved visualization and selection tools make layout tasks easier than ever. 3D Viewer KiCad's 3D Viewer allows easy inspection of your PCB to check mechanical fit and to preview your finished product. A built-in raytracer with customizable lighting can create realistic images to show off your work. About KiCad KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and macOS and is licensed under GNU GPL v3. Mission Statement The goal of the KiCad project is to provide the best possible cross platform electronics design application for professional electronics designers. Every effort is made to hide the complexity of advanced design features so that KiCad remains approachable by new and inexperienced users, but when determining the direction of the project and the priority of new features, the needs of professional users take precedence. Project Governance The KiCad project is governed by a technical committee made up of the members of the lead development team. Most decisions are made by a consensus of the technical committee. When a consensus cannot be reached the final decision is made by the project leader. History KiCad was first released in 1992 by its original author, Jean-Pierre Charras. It has been in continual ... |
