wtf is fritzing-app?

Fritzing is a desktop application for designing and documenting electronic circuits, aimed at hobbyists, makers, and educators rather than professional engineers. It offers a visual approach to circuit design with a low barrier to entry: you drag components onto a virtual breadboard that looks like the physical breadboard you would use when prototyping a real circuit. The same design can also be viewed as a schematic diagram or converted into a PCB layout ready to send to a manufacturer. The application comes with a library of commonly used components, including many parts associated with Arduino and Raspberry Pi projects. This makes it particularly popular among people building small hardware projects or teaching electronics. Because Fritzing produces clean visual diagrams, it is also widely used to communicate circuit designs in tutorials, blog posts, and documentation. Fritzing was originally developed as a research project at Potsdam University of Applied Sciences in Germany and grew out of the Interaction Design Lab there. It was maintained by a Berlin-based nonprofit called Friends of Fritzing, and since 2019 has been maintained by Kjell Morgenstern with contributions from a small team. The software is built on the Qt cross-platform framework, which allows it to run on Windows, Mac, and Linux. The source code is licensed under GNU GPL version 3, and the parts library and documentation are under Creative Commons Attribution-ShareAlike 3.0. This means you can modify and redistribute the software as long as you credit the project and release your changes under the same license. Circuits and diagrams you create with Fritzing are your own, though any images using Fritzing's graphics need a credit. The project's wiki contains developer instructions for building from source.
