In this process I had to design a couple of boards. I’ve been using Eagle and completed my learning (still in process, of course) with some tutorials online.
This assignement was about the re-design of the hello board to which I added a button and a led. I started by reproducing the entire schematics on the schematic view.
In this specific case I also had to import the fab library of components:Right-click to download the svg above - my version of the hello board in the easel/carvey ready mode
After that, I added the new components.How to add new components to the schematic Final result - schematic
When finished, I jumped into the board view, where all the components were a mess waiting for a bit of “graphic design”. As I don’t know much about electronics, one of the first things I had more dificulty doing was defining the rules. Those rules depend mostly from the way you expect to produce the board. In this case it was a milled prototype so I couldn't expect fine clearances and I had to play defense. I was expecting to use a 0.4 mm mill and a 0.8 mill to cut the board out.
After these steps, the game begins because you will have to fit everything into one side of the board. I usually try to place all the components with the yellow fin link lines pointing at the other end. After that you can trigger auto-route once just to have an idea of what is the proposal. Maybe you’ll be surprised. Most of the times you don’t.
So, just start throwing lines. Remember to avoid 90º corners and to be aware of the rules you defined. This is a challenging and engaging iterative process. I think my boards will always get better with training.Programming it The result.
