Noise from VRM

[peronis]

Hi all,

We have a electrical noise coming from our VRM. The only component wired to it is the router.

We switched to another VRM we had, and the same problem exists. Is this a problem, or is it normal for the operation?

If it isn't normal, then I think it might be interference from our wire runs, since we have the wires from two motors and 3 solenoids all running in a bunch from one side of the robot to another. I hear it though even if the robot is disabled and no current is going through them. So, I ruled this out.

Thoughts or suggestions would be helpful.

Thank you
