//I have two version of this display, one from an original Arduino kit and one from Aliexpress, and the display case (the black part) differ in size so I placed an option to select wich one to visualize. The original one size 26.5x71.5x8.5mm while non original one size 24x71x7mm.The board and pin positions are identical.
