A 5 kΩ, thumb-wheel type, potentiometer at RV1 provides continuous, variable resistance input for user
applications. The output is the result of a voltage divider that changes as the thumb-wheel is turned. The
potentiometer is connected between VDD and GND with the center tap providing the divider output. This
center tap is connected to the MCU on signal AN0. The potentiometer may be disconnected from AN0 by
means of the POT_EN option header, shown in
