Hi all! I'm hoping this is a well known and easy issue to solve... I have some code that was running fine using this Adafruit OLED (128 x 32) Picture Here
The board is a little large, so I have purchased some of these from AliExpress - they should be the same kind of OLED, same size and same communication type. Though when I plug in the new display, it doesn't start up... Is there an obvious problem here or something that requires some proper thought..?
