Electronics Design

I start with this image, after loading the fab lib, I "add" the components in the workspace, and then with the "net", "name", and "label" I connect all the components based on this picture.

Then I added a button with a pull-up resistor to the PA7 pin, and the led with a 100-ohm resistor to the PB2 pin.

I have to set the tool diameter for the traces in 0.15 mm.

Changing tool diameter in Fab Modules

Some of the GND pins doesn´t appear in the traces.

Trying to get correct milling traces, I try the isolate comand in the info menu.

Design Rules

Finaly I understand why design rules are so important.

With new values in the design rules I export a better PCB design.

I tweak the wire size to 18mil in order to get better traces witouth changing to much the mill size in Fabmodules.

Finally, the PCB looks great in FabModules with a 0.31 mm tool diameter.
