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 the browser—seamless automatic upgrades.

Circuit Simulator

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

Online PCB Design

You could still operate quickly and layout smoothly with multiple layers and thousands of pads.

The system is very stable, reliable, and easy to learn. The user interface is enjoyable and responsive operation.EasyEDA has a rich library of thousands of electronic components (for circuits, printed circuit boards, and 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 tool’s main features and a Simulation ebook, introducing circuit simulation in EasyEDA using ngspice.

The following video briefly presents the features of EasyEDA tool:
