accidentally plug the 5v into GND and VCC to GND and burn a bit

i was following a diagram online and i accidentally plug the into the wrong place . i did not realise the picture was wrong until i smell something burning . the tape of the display have a hole in it. i don't know whether is operational or not . do i need to buy a new one or not?

Definitely buy a new one. :astonished:

Banggood used to have a notice with the description of some of their OLED displays mentioning the fact that you had to be careful about the power connections since they were not the same for all of the models.
