Dimensions of Components in Curt Spectrum Trailer Brake Controller C51170

Question:

Do you have dimensions for the control knob base diameter and the controller? There are 10 LED that are used to max braking level. Does that mean there are 10 levels that can be selected?

On the Curt Spectrum Trailer Brake Controller # C51170 the round base of the rotary knob component measures 1-3/4-inches in diameter and has a depth of 1-1/2-inches. The main control box component measures 3 x 3-1/2-inches overall and has mounting holes spaced apart on center at 3/4 x 2-3/4-inches. I made a photo with these dimensions which is linked for you.

The Spectrum does have a 10-LED display but the controller output is not limited to only 10 specific power and boost settings.
