8. Electronic design¶

Group assignment :¶

Use your laboratory test equipment to observe the operation of a microcontroller PCB
Send a PCB to a board of directors

To see our group assignment click here

Individual assignment:¶

Use an EDA tool to design a development board to interact and communicate with an embedded microcontroller, produce and test it
Extra credit: try another design workflow
Extra credit: design a package for it
Extra credit: simulate its operation

Eagle¶

To download Autodesk Eagle click here Once on the site select the Windows option and click on Download.

After installing the Eagle software on your desktop or in the folder of your choice, open it and you should see the following:

Click on File > New > Schematic

Click on the Add Part button and select the required component

Add the following components to the reserved space and use the Net tool to connect the various components

Click on Name and rename the green lines as shown below.

When you finish, you should have a correct schematic with all links well defined

We have finished the drawing of the electronic schematic and now we will draw the PCB.

Click on the Generate/switch to bord button and click on Yes you should have the following display.

place your elements in the black area that appears
For connection, use the Route airwire

We have chosen a Widht = 0.02 inch

To draw contours, choose : Line > in Layer, Dimension and draw the contour of your choice

Here is our electronic schematic and our PCB after we finished our design.

Generation of PNG files for the traces and the board outline¶

Once I have all the components placed and the tracks together, I need to export the file as a .PNG. But first we need to be only exported the tracks, and after the outlines. To do this we followed the process below:

Click on Layer Settings, go to Filter select Used Layers and uncheck all but Top and click on OK.

Go to File > Export and click on Image a window will open, click on Browse… to choose the file type and location, select Monochrome with Resolution = 1000 dpi and click on OK.
