Kicad is an open source (GPL) software for the creation of electronic schematic diagrams and printed circuit board artwork, and consists of a set of four softwares and a project manager: Eeschema (schematic entry), Pcbnew (board editor), Gerbview (GERBER viewer), Cvpcb (the footprint selector for components used in the circuit design) and the Kicad project manager. The Linux and Windows versions can be downloaded here.
