      Hello,
      I use a PCA9685 LED / servo controller with i2c on a rotary knob M5 Dial.
      A level shifter is mandatory because the S3 Stamp is not tolerant to the 5V from the PCA.
      There are two modes:
      PWM with values from 0 to 100 -> 0 - 100% pulse width (50 Hz)
      Servo controller for standard servos with values from 101 to 200 -> 90 degrees servo rotation with adjustable zero and range

      i2cMaster

      enjoy

        Use the dedicated servo unit and you don’t have any level shifting problems to worry about
