I bought a Raspberry Pi and I noticed some of the routings are not straight lines but instead they make a funny ondulatory shape (see picture at the right and bottom of the processor).

I'm not sure the reason of this shape. I have two guesses:

  • It makes this signals slightly delayed compared to others.
  • It makes the the route a certain exact length which would avoid resonance frequencies.

Are my guesses correct? Or this shapes are for something else?

You are correct, these meanders are used to get exact timings of the signals. It is necessary to match differential pairs with high speed signals.
