It powers up but I can see nothing on the OLED screen. How can I detect and /or investigate whether there is an hardware problem? Is there a scheme of this board? Besides, I was able to connect the Wi-Fi and can see the OS through the web app. I am going to test it with the elettrovalves in the coming days. Thank you and regards, Matteo.
