MeowCAD is an online free and open source electronic design application tool. Its focus is on schematic and PCB design for electronic circuits.
MeowCAD is the first completely free and open source, software-as-a-service, electronic design tool and provides a free and open source alternative where there wasn’t one before. Ultimately, the value of an online electronics design community comes from its members. People are encouraged to fork the project, stand up their own servers, or just use MeowCAD directly to create their own electronics projects and share with the community.
Some fun stuff for the maker crowd.
