Jetson.GPIO nano HIGH voltage

Hello,

I have question regarding Jetson nano GPIO. It is said in the developer kit documentation that J41 support GPIO and operate with 3.3 voltage level. However, by using Jetson.GPIO library I noticed that when I turn the pin on (GPIO.HIGH) the voltage level is 1.6 and not 3.3, when I turn off (GPIO.LOW) it is getting 0.5.

So, could anyone explain me that, or maybe my Jetson nano is broken?

Thanks in advance
