Circuit simulator and PCB design software - EasyEDA

EasyEDA 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.

I looked their site over and it seems that the restrictions are pretty reasonable.

Unlimited open source projects no more than 2 private ones at any one time on the free version.

I did not see any size or pin restrictions although their PCB order page only goes to 6 layers so that could be a restriction of the board layout capabilities as well.

And they also allow you to download Gerber files which a lot of the free ones tied to a board vendor do not allow.

The tools seem pretty good although not clear to me yet about various autorouter capabilities.

Nice rats nest though and the simulator has great potential capability (depending on how many and how well various chips are simulated).

Definitely seems to be worth taking a closer look at.

Best regards,


This could be a great asset to us without the size and layer restrictions of the free version of Eagle who's interface leaves a bit to be desired in any case.

It is a very practical design tool for me. I create my schematics on EasyEDA. I use it very much. One of the advantages is certainly that you can edit the schematics wherever an Internet connection and a current browser is available. I satisfied with this free tool.

Could not find Toshiba RF MOSFET's in PW-X package in its library

No Atmel SAM 4E

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.

Best Regards,

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 :)

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

Comment by Gary McCray on February 26, 2016 at 6:37pm

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.

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.

Comment by Thomas Butler on February 26, 2016 at 9:24pm

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!
