    Hi Lukas,

    thank you for your reply. It pointed me to the problem.
    As the Nextion Display requires more power than the pinheader supplies I connected it to an external 5V power supply.

    Now, I connected the 5V GND’s of the external power supply and the Controllino pinheader.
    Now i am getting a clean signal.

    Thank you for directing me towards the solution!

    Best Regards,

    Max
