The SparkFun Rotary Switch Potentiometer Breakout is a small board the allows you to add resistors to a 10-position rotary switch, turning it into a potentiometer with 10 discrete steps. Multiple applications require potentiometers that are hard to find due to specific resistance values or custom tapers, the Rotary Switch Potentiometer board allows you to populate your own resistors to help match situations where ordinary parts aren’t available or suitable. Specific resistors can also be used in situations where you want distinct steps or selections, such as being able to consistently select to a value.
Each Rotary Switch Potentiometer Breakout provides you with nine spots on the board for resistors (positions 1 through 9). These resistors are bent like a hair pin, and soldered in place “standing up.” On the opposite side of the breakout you will find three pins to attach leads or a connector which include, CCW (Counterclockwise end of resistor string), W (Wiper), and CW (Clockwise end of resistor string).
Note: A 10-position rotary switch is NOT included with this breakout. Check the Recommended Products section below for the correct switch.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

... thus, it's only function is to make the rotary switch easier to install. Which it does. I suppose if I had done a million such installs with and without I could say something more enlightening. But I do like it.
Needed it to be reliable and it was.
Loved it!!!. And thanks for the easy to use math formula calculation. I would have been many hours figuring out a formula vs an IF then ELSE or case statement. Good work SPARKFUN
Now if only I could solder better life would be good.
The rotary switch fits perfectly onto the breakout panel. With it, it is so much easier to hook up the connections. (Without it, soldering would be quite painful.)
