FidoCadJ

FidoCadJ is a great free and open-source software that makes designing electronic circuits super easy. It's built for users who want a clean and simple workspace to create their designs. Just a heads up, since it's a Java-based app, you need to have Java installed on your computer to run it.

Wide Range of Components

This software comes loaded with tons of electronic components. You can pick from electrical symbols like switches, transformers, conductors, and circuit breakers. It even has power converters, signaling devices, measuring instruments, and relays!

Add More Elements Easily

You can also insert cables and connectors along with inductors, resistors, gates, boards, ceramic capacitors, diodes, bridges—basically everything you might need! If you're working with electric machines or batteries and generators, FidoCadJ has got you covered.

User-Friendly Features

The app makes it super easy to access all these components. You can preview them in a special pane and drag them into your project with just a couple of clicks. Plus, if you want to find something specific in the list of components? No problem! There’s a search option just for that.

Edit Your Designs Effortlessly

You can enable or disable the grid to help line things up just right. Zooming in or out is simple too! Also handy are the undo and redo features for those little mistakes we all make. Basic editing options like cut, copy, and paste are included as well.

Add Custom Touches

Want to add some text messages? Or maybe lines and curves? FidoCadJ allows you to include Bézier curves, polygons, ellipses—whatever fits your design best! And once you're happy with your circuit design, you can print it out or export it in formats like PNG, JPG, SVG, EPS, PGF, PDF—you name it!

High Quality & Low Stress on Your System

We’ve tested the tool out ourselves and found that it produces excellent image quality without any errors popping up during use. Plus it doesn’t bog down your computer's performance at all!

Create from Scratch with Ease

If you're looking for an intuitive layout combined with useful parameters for creating electronic circuits from scratch, FidoCadJ is definitely worth checking out!
