fritzing/fritzing-app
4,732View on GitHubFritzing is electronic circuit design software used for documenting hardware builds. It functions as a hardware documentation tool and a printed circuit board layout tool, allowing users to create visual representations of circuits through breadboard, schematic, and board views. The software includes a dedicated electronic component modeler for creating digital representations and custom parts for component libraries. It supports a full manufacturing workflow, enabling the translation of digital circuit sketches into professional board orders through integrated production services. The appli
Fritzing is a genuine open-source PCB design tool that covers the core requirements—schematic capture, PCB layout, a component library, Gerber output, and 3D preview—with a built-in autorouting feature, making it a solid fit for designing electronic circuits.

7,244View on GitHubLogisim Evolution is a digital logic simulator and schematic editor used for designing and verifying digital circuits. It functions as a tool for digital circuit design and real-time logic simulation, allowing users to create schematic representations of electronic hardware using gates and registers. The software distinguishes itself by providing hardware description language tools that allow for the definition of custom component behavior and the translation of visual schematics into synthesis-ready code for FPGA hardware deployment. It also serves as a bridge for physical hardware integrati
Logisim Evolution is a digital logic simulator and schematic editor for designing and simulating digital circuits, not a tool for PCB layout or physical circuit board design, so it does not match the required PCB design features like autorouting, component library, Gerber output, or 3D preview.
