Drop in remote stepped attenuator

Hi All,

I found what I think is a neat remote stepped attenuator that is mis-described on AliExpress and Ebay and drops into the place of a large pot:

I prefer a remote volume control but typically want something fancier than a cheap motorized pot. The nice thing with these is that unlike a MUSES72320 kit or various other options, they drop in to the same physical space occupied by a standard pot in many preamps or integrated amps. If you want to run the display, it doesn't require as much hole as other options.

They are affordable (though they have gone up since the $43 I paid for my first one) and work on a USB supply (at least the two I got--though not the ones in the pics--say 7VDC but have a jumper where you can run them on 5VDC).

I've been looking for things like this for a while, but missed it for a long time because I typically search for attenuators. If I'm a goofball and misunderstanding this part, feel free to let me know.
