I’ve been using the Open Source tools found on Linux for a number of projects. A current project requires a printed circuit board be made. Using gschem to capture the schematic then pcb to do the layout I have created what I needed for this project.
Both tools are members of the gEDA family of electrical engineering tools.
Thinking your project may need a board? We can offer the design services for the board or we can install & teach your designer how to use these tools.
