Potentiometer
A 5k ohm, single-turn, 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 input
AN0. The potentiometer may be disconnected from AN0 by means of the POT_EN option
header.
