Eagle has libraries that contain information about each component: geometric layout and logical output pins. Components used at Fablabs were not available on the already-installed libraries, so I had to install the Fablab components library first.

With a combination of looking at how wiring was done in the original hello.FTDI board and looking up the datasheets of each of the components , I was able to make the logical connections between the components in schematic mode.

Wiring is really a form of art, and takes a long time to master properly. Following the original Hello.FTDI board wiring it was possible to route the board without any extra overlapping wires I exported images: File->Export. Settings: Monochrome ticked, resolution 500 DPI

Milling

After creating the PGN file, go to mill card , for this use the following parameters : Used Roland Modella Sets " -Z = 0.12" and " offsets = 2" (the offset is the time to pass the mill ) , select option "mill tractor 1/64 ) finally the option " make path " Sets the X and Y axis in ny case ( 20 , 13 ) will be Observed as the trace and select "make rml " We click on "Send it "

Soldering

The welding process, is very difficult because the components are very small, a first card could not be used because of problems of distances between lines. The second card was more appropriate and with it the card is full.
