On the TinyScreen+, I have it connected to the terminal block breakout. I am using lines 0 and 1 for Serial communication. However, I am experiencing a lot of noise on this. The lines are extremely short and I haven't had this kind of issues in the past with other Arduino hardware.

I do not have any other boards connected. Are there some issues on these pins that I should be aware of?

I would like to know why I can get more information and clear enough to introduce me?
