To get started with the EasyEDA design tool, you need to visit their website and create an account.

Design a schematic diagram

After you have opened the website login and entered the login details, you can begin a new project. Create a new project and navigate into the drawing board and choose the components needed from the libraries. If you find it difficult to discover the needed component, search for option like MORE LIBRARIES. This option will help you search for your needed component.

Choose the needed components and start creating the schematic diagram. After this, click on the needed component to choose & click on the canvas.

Check the connections

It is important you check every connection once you have finished the designing the schematic. To achieve this, you will have to create a folder like Nets on the Design Manager tab. If components are not well connected , there will be automatic warnings. Some errors are likely to occur during the circuit design. Some of these errors include overlay of contact pads and vertical paths to the contacts.

Simulate the circuit

You will see a green button on the menu’s top once you have saved the circuit. Select the green button for simulation and click on “run the document.” Once you have done the simulation, you will see the diagram at the terminal you have selected.

Converting PCB layout through EasyEDA

Click the option “project to PCB” once you are in the schematic board. Once you click it, you will see the PCB design board page open. This page will ask to choose the most suitable components to continue if any components over the schematic diagram has no PCB traces.  

What is Cadence Allegro PCB Design software?
