Free electronic design automation software

KiCad ( ) is a free software suite for electronic design automation (EDA). It facilitates the design and simulation of electronic hardware for PCB manufacturing. It features an integrated environment for schematic capture, PCB layout, manufacturing file viewing, ngspice-provided SPICE simulation, and engineering calculation. Tools exist within the package to create bill of materials, artwork, Gerber files, and 3D models of the PCB and its components.

Fritzing is an open-source initiative to develop amateur or hobby CAD software for the design of electronics hardware, intended to allow designers and artists to build more permanent circuits from prototypes. It was developed at the University of Applied Sciences Potsdam. Fritzing is free software under the GPL 3.0 or later license, with the source code available on GitHub and the binaries at a monetary cost, which is allowed by the GPL.

Tinkercad is a free-of-charge, online 3D modeling program that runs in a web browser. Tinkercad is widely used in schools and beginner maker communities because its simple interface allows users with little or no prior experience to learn basic 3D modeling concepts. Since it became available in 2011, it has become a popular platform for creating models for 3D printing as well as an entry-level introduction to constructive solid geometry in schools.
