EasyEDA is an easy to use circuit design, circuit simulator and PCB design that runs in your web browser.

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 are:

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. 


Design a Raspberry Pi add on board

In the project area there are several open source pcb circuit designs users have made for boards that are for use with the Raspberry Pi computers. Here are some examples:

Raspberry Pi Breakout Board v1


Raspberry Pi Power Controller


Raspberry Pi Motor Driver Board v1.0


SidPi Module

I have very limited time currently for the comments, so you will probably get a very slow response for questions I know the answer to. If I need to set up a Pi to check your issue or request then I am unlikely to have chance to spend time on this.
I will continue support once I can spare the time again.
Thank you for your interest
