2.5.5 POT - Rotary potentiometer
For identifying the rotary potentiometer on the board, see position (34) in
section Positions of interfaces and operating elements [ } page 8].
The 3-terminal resistor forms an adjustable voltage divider (measurable via
ADC3_IN2), e.g. for manually controlling the speed of a motor.
