The Fritzing application is an Electronic Design Automation software with a low entry barrier, suited for the needs of makers and hobbyists. It offers a unique real-life "breadboard" view, and a parts library with many commonly used high-level components. Fritzing makes it very easy to communicate about circuits, as well as to turn them into PCB layouts ready for production. It is particularly popular among Arduino and Raspberry Pi users, and is widely used in education and creative tinkering.

Folder Structure

  • bins - Part bins (.fzb, aka part libraries) are collections of parts, most importantly the "core" parts bin, and vendor-specific collections.

  • help - End-user documentation included with the app. This should really be moved back to the website.

  • parts - All the part definitions, including meta data (.fzp) and graphics (.svg), as well as some utility tools. They are kept in a separate repository at and only linked from here.

  • pri - Submodule definitions for Qt

  • resources - Binaries and definitions that are supposed to not be touched by users, such as fonts, images, special parts, etc.

  • sketches - Example circuits/sketches shipped with the application

  • src - Application logic!

  • tools - Utility tools for making releases, converting parts, etc.

  • translations - Language translations


The Fritzing app is maintained by the Friends-of-Fritzing e.V., a non-profit foundation based in Berlin, Germany. The project has grown out of a state-funded research project at the Interaction Design Lab at Potsdam University of Applied Sciences.

The core team consists of Prof. Reto Wettach, André Knörig, Jonathan Cohen, and Stefan Hermann. Many fantastic people have contributed to it over the years.

The Fritzing app is written on top of the Qt cross-platform framework.
