Sad to see Soekris gone, but it was not unexpected.
I've seen lots of posts about alternative fanless/industrial SBCs, but I
have never seen CompuLab mentioned. I have a FitPC2 and an AirTop and
they are awesome.
They aren't cheap, but they are solid.

I was also one of the first to order the net6501, but the first models
were the -50 and the subject model is a -70 (not released until many
months later). My -50 has been going strong since day one and I've been
very happy with it. I've had to update the flash several times, and I do
pay
Jan,
It is more likely that the noise you are hearing is coming from the
magnetics rather than from any capacitors. There are planar
transformers in the switching power supply and the Ethernet interface.
Sometimes the transformer core material has a natural frequency harmonic
in the audio
Attila,
Thank you for the detailed post. It is clear that you have some
understanding of best practices regarding digital PCB layout. However,
you've made a number of assumptions and generalizations. Are you
certain that there are no power and ground layers within the net5501
multi-layer
