I got the 1.14" ST7789 Display. Hooked It up, but couldn't get it to work properly. After a bit of googling, I came across a forum post with the same issue as me, that the display only worked while the reset button of the Arduino was being pressed. The forum mentioned, to connect it to 5V, and there we go... working perfectly. So maybe the 3.3V VCC as mentioned in the product description is wrong? Now that it works, I'm very happy with it. Nice and bright and fairly high resolution for a good price!
All OK
