Re: PD Board Noise?
Just to recap everything here with an historical footnote.
1st of all the noise is nothing to worry about. It will change under load and will get drowned out when you get your robot going.
Years ago when they first came out with switching power supplies it was common for them to make noise and annoy people. Back in the day there were devices I could hardly stand because of the high pitched switcher noise.
Over time, two things have happened. 1) switcher frequencies have increased, beyond the range of human audibility. 2) components have improved so that they don't vibrate as much.
Bottom line - don't worry about it.
