5.5 Potentiometer
A single-turn potentiometer is connected as a potential divider to analog input AN000, pin D4. The
potentiometer can be used to create a voltage between Board_3V3 and AVSS0.
Refer to the maker site for specification of the potentiometer (VISHAY with part number TS53 series).
The potentiometer offers an easy method of supplying a variable analog input to the microcontroller. It does not
necessarily reflect the accuracy of the controller’s ADC. Refer to the RX72N Group User’s Manual: Hardware for further
details.
