Description
[EasyEDA][1] is a free EDA tool for individuals and working in a web browser, it requires no any installation. It was designed to provide electronic hobbyists, engineers, teachers, students ... an easy and free access to the EDA. With EasyEDA, **powerful** **schematic capture**, **mixed-mode spice simulation** and **PCB layout** are made in your web browser. EasyEDA has all the features you expect and easily take your design from conception through to production. EasyEDA aims to bring every electronic hobbyist an easier EDA experience. That’s why EasyEDA comes to the world and named EasyEDA.

**EasyEDA free Online EDA**
**EasyEDA features**
Here is how EasyEDA introduces its online PCB creation tool.
[Simple diagram drawing][3]
![enter image description here][4]
Draw diagrams quickly in your browser using the available libraries. The updates will be applied automatically.
[Circuits simulation][5]
![enter image description here][6]
Check analog, digital and mixed circuits with sub-circuits and SPICE models!
[Online PCB design][7]
![enter image description here][8]
With multiple layers, thousands of blocks, you can always work quickly and smoothly arrange your cards.
**Design Flow using EasyEDA**
![enter image description here][9]
You will find below the steps applied to the creation of a blinking LED with 555 ...
**EasyEDA real test**
![enter image description here][10]
**Google Chrome application**
When EasyEDA contacted me to offer me to write this article, I naturally wanted to test this application before accepting the proposal. EasyEDA is available in the [Chrome store][11].
![enter image description here][12]
Once the app is installed if you display the apps (type in the address bar of Chrome: chrome: // apps)
![enter image description here][13]
and you click on the app EasyEDA, then you arrive on the [website of EasyEDA][14]:
![enter image description here][15]
On the left side of the screen, you find symbols that you select when you click on it. On the right side you can choose to draw a schematic or directly a PCB (printed circuit board).
**Draw which circuit?**
For a old former electronics engineer like me, it was easy to find a simple circuit for testing the use of this web app. How about a good old 555? I largely use it during my career, I will use it this time again.
![enter image description here][16]
Click to enlarge (http://www.ohmslawcalculator.com/555-astable-calculator)
And as output I use a LED to « see » what happen…
**Drawing the schematic**
The interface already seen a little higher is very simple to use. Select a component in the left column by clicking it. Move the mouse in the drawing window. Click, you release the component. Click again, you release another one... The space bar and the R key are used to rotate the components. The numbers increment automatically. Here is the diagram that I realized.
![enter image description here][17]
**Circuit simulation**
![enter image description here][18]
if you look at the schematic, you'll see I've added two probes volProbe1 and volProbe2. It is possible to start the simulation by clicking on the icon representing a jogger then **Run the Document**.
You will have to set the parameters in order to observe the curves generated by the simulator. After a few tries, the simulation result appears.
![enter image description here][19]
We can see the charge / discharge of the capacitor and the output voltage. To better see the results I enlarged the image by adjusting the time (µs/div).
![enter image description here][20]
If you look at the 555 calculator a little higher, you will see that the period should be worth 15.385 microseconds ... not bad, right?
![enter image description here][21]
Once verified the proper operation of the circuit, click on the printed circuit card icon and you start the creation of the PCB.
The first step is the generation of the net where the components are connected by direct wires.
![enter image description here][22]
From this net, move the components on the board according to your placement constraints
![enter image description here][23]
Well ... we begin to see what will look like the circuit ... You can now route the tracks.
![enter image description here][24]
You click on the icon representing printed circuit tracks and go!. The first window asks you information on the size of the tracks. You can also avoid routing some tracks as the ground for example, if you are planning to use ground plane ... At first simply confirm by clicking on RUN.
![enter image description here][25]
![enter image description here][26]
With the 555 diagram, routing takes only a few seconds ... it certainly will not be the case with a more complex schematic.
![enter image description here][27]
The color of tracks indicates whether they are above or below the circuit.
![enter image description here][28]
We can add tracks, change the width, move some tracks by clicking on the active points, for example I shifted the blue one that passes under R4 and that seemed too close to the pad. I also do a U-turn to LED D1 (bottom right) because the tracks crossed. In this case you must restart the routing and lose your changes to the tracks width. It is therefore necessary to redo tracks width modification. Please ensure that all components are correctly positioned before changing tracks width !
You can insert an image, a logo on the PCB :
![enter image description here][29]
The different layers of the board are displayed using a color code. Here the yellow color indicates that we visualize the top silk layer printed on the top of the circuit.
![enter image description here][30]
We can finally see a photographic view of the circuit to have an idea of what it will look like.
![enter image description here][31]
**More advanced examples**
Well, okay, my basic 555 circuit is not very representative ... It allowed me to test the workflow and verify the operation of this free tool.
Of course with a little more time (and a lot more experience) you can produce circuits quite professional, examples of which are available on the website:
![enter image description here][32]

4 ports Switch
![enter image description here][34]
STM32 board :
![enter image description here][35]
![enter image description here][36]
![enter image description here][37]
![enter image description here][38]
Use open source modules
EasyEDA also provides component libraries that allow you to directly integrate components from multiple vendors :
![enter image description here][39]
![enter image description here][40]
![enter image description here][41]
To illustrate this I have chosen an LED equipped module (SeeedStudio). It is possible to integrate this module to your project :
![enter image description here][42]
![enter image description here][43]
![enter image description here][44]
![enter image description here][45]
EasyEDA has a rich library of thousands of electronic components (for schematics, PCB and modeling) and tens of thousands of examples of schematics! Anyone can use this library and enrich it. You can also import drawings made in Altium, Eagle and KiCad and edit in EasyEDA.
It includes the Arduino in all forms such as R3:
![enter image description here][46]
**Create the PCB**
When you are satisfied with your circuit, Fabrication Output icon directs you to the page where you can choose to download the Gerber files (if you want them manufactured by another manufacturer) or continue by ordering the printed circuit to EasyEDA.
![enter image description here][47]
![enter image description here][48]
**Tutoriel**
A comprehensive [tutorial][49] describes how to use EasyEDA. An [online ebook][50] describes how to use the simulator.
The tutorial is completed with videos that explain the operations, such as the diagram creation :
![enter image description here][51]

One can also create professional schematics:

**Conclusion**
During my tests, which lasted several hours, EasyEDA proved stable, reliable and relatively easy to learn as it is pretty intuitive. One regret though, is that when you have routed and then retouched widths tracks, it requires to restart the routing ... and to redo the track widths modifications. No matter if it was a small circuit like mine. A little annoying if you have a complex drawing !
The availability of a large number of open source modules is more significant, as well as access to thousands of shared projects such as [clocks][56] or [speed controllers][57] ...
The availability of a tutorial and an ebook for the simulator facilitate the handling of this online app.
Completely free for electronics engineers, educators, students, makers and enthusiasts. Why not try this free and powerful circuit design software. You will find it is interesting and unique.
