FidoCadJ is a simple vector graphic editor. You can draw whatever you want, and FidoCadJ comes with a large library of symbols related to the electrical and electronic engineering.
Its drawings can be exported in several graphic formats (PDF, EPS, PGF for LaTeX, SVG, PNG, JPG). Even though it is very simple to use, FidoCadJ can be useful as a basic schematic capture and electronic design automation (EDA) software. FidoCadJ is inspired from the old FidoCAD (without “J”), which was a vector graphic editor for electrical schematics and printed circuit boards. FidoCAD used a file format containing text, very compact and perfect for copying and pasting from/into newsgroups and forum messages.
You need a computer with Java 9 installed. Any operating system will do (Windows, Linux, macOS,…). You can also run FidoCadJ on an Android tablet or cellular phone (version 4.0 at least is required).
This is free and open source software.
