[Skimmertalk] [RBN-OPS] Alternate 5V power supply for Red Pitaya?

[Björn Ekelund]

I have been using no-name RP 3 power supplies with good results. They are
typically rated at 2.5A.
Some need the 5V cable run 4-5 times through a suitable (i.e. active below
30MHz) clip-on ferrite to be completely quiet.
