Jetson Nano GPIO & PWM Signals

Hello guys.
I’m working on relay and servo motors,
When I set high to pin 13, the servo motor(pin 32) starting at the same time. When I measure other pins it shows 1.6V.
What am i missing ?

hello enesbatin97 ,

there’s level shifter,
could you please access this application note for Nano’s 40-pin expansion header usage considerations.
