Circuit simulator and PCB design software - EasyEDA

3689682886?profile=originalEasyEDA is a free, zero- install, cloud-based EDA tool, designed to give electrical engineers, educators, engineering students and electronics hobbyists an Easier EDA Experience. It is easy to use circuit design, circuit simulator and PCB design that runs in your web browser.

Features of EasyEDA:

Cool Schematic Capture

Draw schematics quickly using the available libraries on browser. Seamless automatic upgrades.

Circuit Simulator

Verify analog, digital and mixed signal circuits with spice subcircuits and models!

Online PCB Design

With multiple layers, thousands of pads, you could still operate quickly and layout smoothly.

The system is very stable, reliable and easy to learn. The user interface is very pleasant and responsive operation. EasyEDA has a rich library of thousands of electronic components (for both circuits and printed circuit boards, and for modeling), and tens of thousands of examples of schematics! Anyone can use this library and expand it. It also can import existing designs done in Altium, Eagle and KiCad and then edit them in EasyEDA .

Moreover, another outstanding feature of EasyEDA is that users can access to Open Source modules developed by thousands of electronics engineers.


There is a tutorial explaining the main features of the tool and a Simulation ebook, introducing circuit simulation in EasyEDA using ngspice.

The following video briefly presents the features of EasyEDA tool.

  • KiCad does have some nice features, but all of slick the bells and whistles are negated by the crappy footprint management scheme, and forget using cloud based CAD. It runs at the whim of the Internet connection. If I want to work on my project on my laptop away from WiFi or the Internet; forget it.

    And I must add, KiCad crashes at least once an hour! You get what you pay for. If it doesn't run, it is of no value. Unfortunately, this is the main nexus of FOSS; just like flight controller software. Nobody job is on the line if the product does NOT work. Nobody is accountable. Best bet is to pay the $$$ and get a product where the creator has liability!

    Dumping KiCad off my system today!

  • When designing a board, one SHOULD have an idea which footprint is used before laying out the board. I do NOT want to spend time nor have my staff spend time searching for foot prints for which they are probably standard or there are probably only two or three variations. KiCad is a hodgepodge or hetergenous programs. As with most FOSS, it is a kludge that was not designed as a homogeneous system. Unfortunately, FOSS software has the one disadvantage of on ongoging piling new great features on top of an old disfunctional core.

    As far as EasyCAD, what a klunk! No designer in their right mind is going to want to risk their designs in "the cloud" where the designs are only accessible if there is a working Internet connection. The EasyCAD program is klunky and last intuitiveness. No right mouse for menus! must manually move the mouse over to the "super" duper menu!

    In addition, I don't see that KiCAD nor EasyCAD links the schematic and PCB in real-time; cannot click on a component in the schematic and see where it is on the PCB!

    Not to mention, the cloud operator or anyone with access to the cloud's system can access your files (note Apple encrypts YOUR iPohne data with THEIR key and not yours. If you run auto-backup to their cloud, YOUR data can be viewed by anyone with Apple's decryption key.

    I'll go ahead and pay my $189 for a professionally developed and MAINTAINED circuit board CAD package.

  • One of these days I will be able to type a simple sentence without skipping a word or two. That should have been:
    ""Kicad/EasyEDA is a much better "thinking" tool than Eagle. Eagle is great if you already have the exact part as it exists in the library - or all the footprints for all the versions - but I like the "make a schematic symbol first, worry about the footprint later" ease that that Kicad/EasyEDA has.""
  • I disagree. It's a PITA to go find all the footprints. Usually a project only requires a few specific footprints the designer needs to pick such as a CPU's. You SHOULD have the exact part because the you will know if it is even available!

  • Kicad/EasyEDA is a much better "thinking" tool than Eagle. Eagle is great you already have the exact part in the library - all the footprints for all the versions - but I like the "make a schematic symbol first, worry about the footprint later" ease that that Kicad/EasyEDA has.

  • Already using KiCad and I agree completely, great package.

    Still it is nice to have an easy to use well featured on line package and easier to get started with than KiCad perhaps for more occasional use.

    Eagle's free version was really a major spur to initial Ardu and Android development and many bits of hardware today still conform to it's board size and pad limitations, but as a product for new development, it is now yesterdays news.

    KiCAD is indeed an excellent package.



  • I was hoping someone would mention KiCad. Top notch and open-source, endorsed by CERN.  @piotr_esden-tempski +1.

  • I am not sure why anyone would still use Eagle, but this (EasyEDA) surprises me even more. Since version 4.0 KiCad became a very strong solution for simple and complex board design that can even compete with top of the shelf commercial packages. No size or layer restrictions, large community of users, runs on all three major platforms and does not require internet to be usable.

    Just my 2 cents :)

  • Not surprising that their circuit library is incomplete, there are a lot of components out there and new ones all the time so having a complete library is nearly impossible without an unlimited budget.

    At least they make it possible to add new components relatively easily which is really what is most important.
