Hi, I recently bought a micro computer: Arduino Nano 33 BLE Sense Rev2 and 2 pieces of a transparent 1.51" OLED screen from DFRobot. I want to connect both screens to the Arduino, but I can't find a good wiring diagram to do it. someone would be able to help me and if so, is it possible to help me with the code to see if everything works?
What are the connections for just a single screen?

A link to the OLED would be useful...
Hi, @erwoj
Welcome to the forum.
This site has all the info you will need to get one screen going, do that then think about the second.
Do you project in stages.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom..

Use 3 different pins for CS, RES and DC of the second screen. The others are shared by both.
Logically, adapt the code in the second screen class definition for the 3 pins you use.

Thank you very much for your answer, but i dont know even how to connect one of these displays
Thank you very much for your answer, I understand everything but I don't even know what pins to connect one of these screens to for everything to work.
Have you read the information from dfrobot that you (and @TomGeorge ) have linked?
Or are you just wasting our time?
Contradiction, just a little?
Hi, @erwoj
PLEASE read the posts.
