crasbe: what do you mean ?
Oh, there are serval problems, I think.
Both USB-Lines (DP and DM) are too far away from each other. The idea of differential potentials is missunderstood. If DP is high, DM is low; when DP is low, DM is high.
This behaviour protects the data against electromagnetical influences.
DM- and DP-traces are about 15cm long, but about 3mm separated from each other. Better would be about 1mm or less.
Also: Why is there no shielding on the opposite side of the traces? They are completely free to send and recive em-fields. Nearly no protection. :roll:
The power-supply is also not quite good IMHO. It's absolutely NOT state of the art. It is 70-80's style...
Also there are serval known fixes, you could edit it in the gerber-files.
There will be a new project, which is based on the thylacine design, but with new components. (Not directly my work.)
