As the world around us moves to the cloud, so too do some powerful EDA tools available on the cloud. EasyEda is one such tool, facilitating schematic drawing, spice simulation (an open source, general-purpose analog circuit simulator), and PCB layout.

EasyEDA is an easy and powerful online PCB design tool that allows electronics engineers, educators, students, makers or enthusiasts to design and share their own projects. It is a design tool that integrates LCSC component catalog and JLCPCB PCB service to help users save time turning their ideas into real products.

The program has more than 70,000 diagrams available in its web database of more than 15,000 Pspice libraries. Since the application is built on the cloud, it offers the convenience of portability. Another advantage that comes with cloud applications is cross-device compatibility.

EasyEDA's outstanding features include:

Simple, easy, user-friendly and powerful general drawing capabilities
PCB layout
Work anywhere, anytime, any device

2. PCB123

This is Sunstone's free circuit drawing software. You can do almost all your needs from design to construction using PCB 123. PCB123 offers 500,000 parts with a great search function to access them all while drawing. Datasheets of selected parts are available. The cool feature of this software is the "real-time" search to select available parts from Digi-Key. After all, this is free software from a reputable company. That's Sunstone.

PCB123 is an application designed to help engineers and those interested in designing printed circuit boards (aka PCBs). It is a CAD utility in its true form not only because of its clear and well-structured interface but also because of the practical tools it provides you.

During setup, you can include or exclude additional components, namely a software development kit for writing plugins that integrate with PCB123, as well as a plugin with an application guide template for creating PCB123 plugins in Visual Studio.

Create boards and customize PCB settings

You are greeted by a user-friendly interface on startup that can be changed. With the help of a wizard, you can assemble a new board by specifying the board name and an optional Netlist file. Multi-page Netlist files can be added, along with Protel, Tango, OrCAD and native PCB123 Netlist files.

In the following steps, you can define the width and height of the board or use a template from the list, as well as set the number of layers and the type of inner layer. Additional board features focus on solder and silkscreen material, PCB thickness, copper weight, and lead-free.

Design CAD diagrams using professional-grade functions

Using PCB123, you can design multi-page schematics complete with components wiring between them and symbols. The working environment is well organized and gives you quick access to all the tools you need to work efficiently. You can view the overall layout of the board or component you are designing, explore 3D renderings, and view layers containing schematics for each component.

PCB designers can automate some tasks. For example, connecting pins from different parts will automatically create wires in between. You can also place application components on the board, minimizing connection distances while maintaining aesthetics.

3. Xcircuit

Xcircuit is a free schematic drawing software from OpenCircuit designs, created for Unix/Linux environments. You can use it on Windows, if you are running an X-server or Windows API. This open source project aims to develop high quality output schematics, ready for immediate publication. There are several versions of the software available. You should read the manual carefully before starting to use it.

4. TinyCad

TinyCad is a schematic drawing software for Windows from SourceForge. It supports circuit drawing, layout development, and circuit simulation. TinyCad is available for free download.

5. Dia

Dia is a basic drawing software suitable for drawing block diagrams. It also provides access to some basic and important components. This software is only for beginners or those who are new to the field of electronic circuit drawing. The software is GPL licensed, created for Mac and Linux.

6. SmartDraw

This free software for drawing electronic schematics is from SmartDraw LLC, a company that develops high-end drawing and CAD software. The free version is a promotional tool for their paid versions. So, you can't expect any great/advanced features in the free version.

7. ProfiCAD

ProfiCAD is a basic, free tool for drawing.

8. Solve Elec

Solve Elec is a free software for Windows and Mac.
