The software aims to support all kinds of circuit simulation types and allows creating schematics and presenting simulation results in various kinds of diagrams. Although Qucs has been largely developed, its developers are still constantly working to improve the application. Includes a huge range of electronic components containing many components and models of semiconductors such as diodes, MOSFETs, pMOSFETs and more


This is an electronic circuit design program. It supports the design of each component and connection taking advantage of its huge library, chips, diodes, resistors, transistors, capacitors, etc. The management of the program is quite simple and is recommended for beginners as well as professionals. Nevertheless, if it is your first time and you encounter difficulties look the Video Tutorials that fully explain its operation.


Absolutely free electronic circuit diagram design program also known as schematics. Supports standard and custom symbol libraries. It supports PCB layout programs in various formats. It is also often used to draw one-line diagrams, block diagrams, and presentation designs.


PCB Creator is based on professional PCB design software and is very easy to use. This is a complete program for designing electronic circuits and printed circuits with great potential. Its use is very simple and those who deal with this type of applications are not going to face any problems. To download the application you need to register.


Draw and share electronic diagrams using a wide range of available materials by placing them in your electronic circuit. Modify their values ​​using the property editor and export them as images in SVG or PNG format. Plugins are available for additional formats. Includes all commonly used symbols such as resistors, capacitors, logic gates and transistors.


FidoCadJ is a free professional application created to help those involved in the design of electronic circuits through a clean and smart working environment. 

You should make sure you have Java installed on your computer before, otherwise you can't run it. It is equipped with a wide range of electronic components so that you can choose the appropriate electrical symbols according to your design (eg switches, transformers, conductors, switches, measuring instruments, relays, etc.). 

In addition, you can place cables, connections, coils, resistors, capacitors, diodes, bridges, electrical devices, batteries, generators, etc. Finally, you can embed text messages, lines, polygons, curves, ellipses, rectangles, connection points, PCB lines. Electronic circuits can be printed or exported in PNG , JPG , SVG , EPS , PDF formats.

The program belongs to a somewhat specialized category. It concerns all those involved in electronic circuits and constructions and will offer them a significant help in this field. 

It is considered one of the best of its kind but the important news is that we can also run it as freeware with some restrictions on the program's capabilities. I should point out that in order to work with the application you should have relevant experience with these types of programs or else to be able to work with it you should have, in addition to the basic knowledge you should have in electronics (know at least the basics in electronics drawing) by studying the Application Tutorial to understand how it works. 

Let me also note that this is one of the top programs for designing and implementing electronic circuits used by both professionals and amateur electronics enthusiasts to design and implement printed circuits from the simplest to the most complex. After downloading the application run it and at some point towards the end of the installation select use as freeware.


Sch3V is an open source circuit design software for Windows. To work with the application open a new document and start designing your own circuit. Click on the Component icon to access the list of materials. 

The library allows you to choose between Logical, Discrete, and Digital electronic components. Select a component and click OK to place it on the board and connect the components. It allows you to work on a 7-layer sheet. 

You can also place any image on the circuit. There is an option to change the sheet size and choose from a sheet size of 640x400 to 3250x2250. Finally you can save your document as .CE3 format or export the circuit as an image in BMP and PNG. 


CircuitMaker is not exactly a free electronic circuit design tool but it is also a creative content community where people design and work together to design circuits and electronic products for a better future. 

CircuitMaker has all the features you need to design high-quality electronics and printed circuit boards, without artificial limits. Best of all, it's completely free, and of course you'll find plenty of reference to ready-made designs. 

Finally, you can define groups to collaborate and design exactly what you want. To enjoy the features of the app all you have to do is register and download the app.



This is an absolutely free open source electronic circuit design application with the application menu also supporting Greek.. With the schematic editor you can create your design without limits. A library of schematic symbols help you get started quickly. You can design professional PCB layouts with up to 32 copper layers.

KiCad now has a router that is capable of routing differential pairs and interactively tuning trace lengths. Finally, it includes a 3D viewer that you can use to inspect your design on an interactive canvas. You can rotate your board to check details that are hard to check in a 2D view.

Multiple rendering options allow you to modify the aesthetic appearance of the panel or hide and show functions for easier inspection. We should point out that although in general although it is not particularly difficult, however, due to the many design options and parameters it provides, we would say that it is aimed more at experienced users or users who have at least some design experience with this kind of applications. On the website of its creator you will find many videos that explain the functions of the program.


High-performance simulation application, with enhancements and models for analog circuit simulation as well as a device library for general circuit simulation. There is a fairly complete set of resources available in the help menu, including examples of its use. 

The schematic drawing program is used to create new schematics or modify the supplied circuits. The program comes with more than 2.000 symbols. These symbols cover most of the integrated circuits and many general-purpose components for circuit design, however, you can also design your own symbols for devices you want to include in the program.

 Overall this is a great program that can help those who are into electronics.


DIYLC is a freeware electronic circuit design tool developed with the help of a large online community of amateurs with a common interest in electronics. It incorporates many ideas that came from people who use older versions of the application and their purpose is to provide you with a simple interface and enough power that will allow the user to create his own electronic circuits. It will run on any computer that has Java installed. It is provided free of charge and can be used and redistributed freely.
