KiCad is a cross-platform open-source software tool for the creation of electronic schematic diagrams and PCB artwork

KiCad can be considered mature enough to be used for the successful development and maintenance of complex electronic boards. KiCad does not present any board-size limitation, and it can easily handle up to 32 copper layers, up to 14 technical layers and up to 4 auxiliary layers. KiCad can create all the files necessary for building printed boards, Gerber files for photo-plotters, drilling files, component location files and a lot more.

It has functions for schematic capture, PCB layout, a 3D viewer, and also a number of external tools that users have developed. There is a calculator for components, track width, electrical spacing, color codes, and even a 'Perform electrical rules check' feature for analysing circuit faults.
