Designing the Schematic
To design the schematic, first, open EasyEDA and create a new project. Then, click on the “Schematic” button to start designing your circuit. In this example, we will create a simple project that uses a NodeMCU board and a few components.
Start by placing the NodeMCU board on the schematic. Then, add the necessary components, such as resistors, capacitors, and LEDs. Connect the components to the NodeMCU board and to each other, following the circuit diagram.
Creating the PCB Layout
Once the schematic is complete, it’s time to create the PCB layout. To do this, click on the “PCB” button in EasyEDA. The software will automatically generate a basic layout based on your schematic.
Next, you can start optimizing the layout to fit your specific needs. Move the components around to create a more compact design, and adjust the size and shape of the board as necessary.
Generating the Gerber Files
After you have finished designing the PCB layout, you can generate the Gerber files. These files are used to create the physical PCB.
To generate the Gerber files in EasyEDA, click on the “Gerber” button. The software will automatically generate the necessary files based on your PCB layout. Once the files are generated, you can send them to a PCB manufacturer to have your board manufactured.
In conclusion, designing a simple project with NodeMCU and EasyEDA is a straightforward process. By following these steps, you can create a custom circuit board that meets your specific needs.
