Fritzing’s PCB View lets you design and export layout files for single-sided, DIY Printed Circuit Boards. You can also export your sketch to Gerber files, and send them to a professional PCB fritzing tutorial arduino pdf service.
Once you get to know Fritzing’s PCB design tools and functions, creating a nice layout will become easier. So your circuit works and also looks great in Fritzing’s Breadboard View. Let’s now have a look at the PCB View. To switch to the PCB View use the Navigator or the View Switcher. While it is very easy to recognize parts in the Breadboard View, the PCB View might look a bit confusing at first glance.
The reason for this is that the PCB View only shows the necessary information needed for the PCB design. This information is shown in different layers. To view or hide layers, use the View options in the menu bar. Selecting PCB View in the Navigator will show a completely different illustration of the same circuit.
The green rectangle is the board itself, on which parts will be arranged. It is automatically placed as you open a new sketch. Parts are shown as footprints, including the Arduino footprint, and you can identify them by selecting or placing the cursor on them to see their labels. You might want to resize the board, or use an Arduino shield or a board with a custom shape.
The first step in designing a PCB layout is arranging the parts on the board. There are some very important issues to consider here, because the location of parts on the board will have a great effect on how successful the routing process will be. Place the parts with the most connections in the middle of the board. If the board is too small, redefine its width and height in the Inspector or alternatively resize the board by dragging its corners. Learn how to design a PCB with a custom shape. Don’t place parts too close to the edges of the board. To avoid short circuits, don’t place parts too close to the USB connector outline on the Arduino Shield.
When designing stack shields, parts’ heights should also be considered. After positioning all parts on the board, be aware that parts are not really connected to each other yet. We would now want Fritzing to automatically generate the connection traces between parts. Click the Auto-route function from the bottom menu bar. If you notice that Fritzing is struggling trying to generate a connection, you can press the “Skip this Trace” button or “Cancel Auto-routing” in the bottom menu while in process.
Such a problem might happen because parts were not arranged properly on the board or when there is just no possible route. Jumpers are connections that need to be soldered with external wires. These are shown as blue connections while traces are shown as orange ones. In the screenshot below, two jumper wires were created after the routing between connectors failed. If you are happy with some of the traces and want to keep them untouched, or you know in advance that some connections need jumpers, you might want to tell Fritzing to exclude some connections in the auto-routing process.
