Hi Doug,
The one that comes with the board is a standard mechanical quadrature encoder with a mometary NO switch.? You can replace it with another quadrature encoder either mechanical or electrical.?? I don't know what the resolution of the standard one is, but it's not super high so you would want to be careful with that.? The switch can be separate (and I am starting to think it would be better this way so that the encoder doesn't change settings when pushing the button).
