Add GND and Vcc copper fills

In this chapter, we will add the copper fills for the ground and Vcc planes. Since we placed the ground tracks in the back copper layer, and the Vcc and data signals on the front copper layer, we will create copper fills in the back and front layers. Let’s start with the bottom layer. Select […]

Exporting Gerber files

We have our PCB ready to export as Gerber files, and upload to the manufacturer! We’ll work on this in this chapter. Let’s start with the Gerbers. Click on the Plotter icon to start the Gerber export process. In the Plot window, we’ll select the layers that we would like to export as Gerber files, […]

Add text labels

In this chapter we will add a few text labels in the silkscreen layer. Text labels provide a convenient way to provide useful information to the end user of the PCB, like the name or model and version number. Select the Text tool from the right vertical tool bar: The text tool button Select the […]

Add a decorative graphic

In this chapter I will show you how to add a decorative graphic on the back layer of our PCB. To better understand what we will achieve in this chapter, let’s start from the end. I would like to add a graphic in the back silkscreen of the board, so that it will look like […]

Create a 2 layer PCB in Pcbnew

In this chapter we will use Pcbnew to work on the layout and wiring of the second project PCB. Start Pcbnew. Type the project details for the canvas legend by selecting Page Setting in the File menu. Type in your own details. Here’s an example: Setting up the Pcbnew project information. The project information appears […]

Hidden pins and the power flag

In this chapter I will explain the concept of hidden pins. To do this, let’s concentrate on the 595 integrated circuit. This IC is interesting because it contains hidden pins. Take a close look at the 595 component. The power pins are not visible. They do exist in the schematic, but they are invisible. You […]

The unconnected component

In the previous chapter, we completed all the wiring, but left IC pin 9 unconnected. In actual fact, we don’t want to connect this pin to anything, as it is only useful if we want to cascade multiple shift registers, one after the other. But, if we do an ERC now, we will get this […]

Create nets and labels

In this chapter we will connect the components placed on the canvas. In the first project, you learned how to use individual wires to connect the pins of the components, manually, using the W key. As your schematic becomes larger and more complicated, this method of wiring will increasingly produce schematics that are difficult to […]
