Cube orange+ ADC-port voltage levels

Hi, I’m using the Cube orange+ with a standard carrier board. In the documentation, it was stated that the ADC IN -pin supports voltages up to 6,6 volts, but it seems to measure signal just up to 3,3 volts. I would like to connect a sensor with a voltage range of 0…5 volts, but not sure can this be done with a standard carrier board. Do I need an external voltage divider to scale the sensor voltage, or does the standard board have one, which can be enabled?

I think the ADC input is 3.3v maximum on most carrier boards.
The Kore carrier has a 6.6v maximum.

You would need a voltage divider like 5.6k and 10k
