EasyEDA is a great free web based PCB tool for anyone involved in electronics design and able to share the work with others. There’s no need to install any software. Just open EasyEDA in any HTML5 capable, standards compliant web browser. Whether you are using Linux, Mac or Windows; Chrome, Firefox, IE, Opera, or Safari. The tool allows you to import an old design from several other circuit maker tools, it has the ability to export the designs and simulation results in .PNG or .SVG formats, and can be a host for your partners and colleagues if they want to work on your projects.
Features of EasyEDA:
Cool Schematic Capture
Draw schematics quickly using the available libraries on browser. Seamless automatic upgrades.
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
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.
There is a video briefly presents the features of EasyEDA tool.
