Getting Started with EasyEDA a web-based PCB Design Software
EasyEDA is a a great and above all free web based circuit design, simulation and printed circuit boards (PCB) design tool for electronic hobbyists, engineers, teachers, students, makers and enthusiasts.
There’s no need to install the software all you need is just open EasyEDA in a web browser. EasyEDA has all the features you expect from traditional electronic design automation (EDA) softwares like OrCAD, Altium, DipTrace among others, this tool easily takes your design from conception through to production.

Creating a new Project
Open the website: https://easyeda.com
Figure 2: EasyEDA website home page
Click on Login, if you don’t have an account you’ll create one for free. You can also login with your existing Google G+ or QQ account. In your account you can manage all your projects, components, personal settings and many things.
On the top right-hand corner, click: New Project
Figure 2: EasyEDA start a new project
In this step, you can create a new project either Public project (Only you can modify this project. Any one can see it) or a Private project (Only you can see and modify this project).
You can create a new Schematic, a new schematic Lib, a new spice symbol, a new PCB and so on.
Figure 3: EasyEDA new Schematic
- On the left-hand side, you can select your components symbols you want to place.
- Just click to select an object then click on the canvas to place it.
- You can move around the component where you want to place it.
- Click the mouse right button to deselect
- In the filter section, type the name of the component that you are looking for or you can click on More Libraries at the bottom to browse and search hundred of thousands of components.
- When you select a component, on the right-hand side in device manage you can change its value.
- Join the components with wire (Hotkey: press W) and complete your circuit.
Figure 4: A simple Circuit
Simulation is very important in any design, it helps you to check the integrity of circuit designs and to predict circuit behavior.
Once you are satisfied that you have done everything to pull in the right models then you can save and then run the simulation. To probe voltages, you can add some Voltage Probes which can be found in the Wiring Tools palette. Figure 5 below shows our circuit, we have placed two voltage probes V In and V out, we also inserted an ammeter to measure the current through our LED.
Figure 5: A simple Circuit with voltage probes and ammeter
Your schematic is ready, so now you can run it.
Figure 6: Run simulation
Figure 7: Transient parameters
- Transient: the time domain response of the circuit;
- AC Analysis: the frequency domain response of the circuit (including an experimental FFT);
- DC sweep: the DC response of the circuit as a voltage or current source or a component or parameter is swept between user specified limits;
- DC Transfer: computes the DC small-signal value of a transfer function (ratio of output variable to input source), input resistance, and output resistance of the circuit;
- DC op simulation: computes the dc operating point of the circuit with inductors shorted and capacitors opened.
After you run a spice simulation which should plot some traces, EasyEDA will automatically open a WaveForm tab like the image below.

Converting Your Schematics To PCB
Most of the time, schematics are created with the aim of producing a PCB. So how do you convert your schematic to a PCB in EasyEDA? The first step you need to take is to click the PCB icon on the toolbar with the title Convert project to PCB
Figure 9: Converting your Schematics to PCB
EasyEDA will automatically load all the package PCB footprints into the PCB editor as shown in the image below. You can also add some mounting holes.
Figure 10: PCB Editor
The next step is to arrange the components inside the Board Outline and click the autorouter icon on the toolbar.
Figure 11: PCB
And lastly you can also add copper area to your board, depending on the layers of your board. Click on the Copper Area tool and draw border around the PCB.
