The RPi GPIO are not 5v tolerant. Wouldn't a voltage divider be necessary here on both the encoder A/B?

Can i use this setup/code with jetson nano board and the same encoder ?

Plz make a vedio raspberry pi program using encoder and stepper motor
Need stepper motor rotate 360 dgree at constant length
