Hello. the problem is the following. when connecting OLED Display to the board, the board is not detected by the computer. It is worth disconnecting one of the two power wires (GND or VCC), the board is immediately determined by the computer. The board works with other modules. Arduino nano board. Connection: GND-GND, VCC-3.3v, CDA-A4, SCL-A5 / when connected to 5V, the board generally starts to smoke. Noticed one feature. On similar displays from other vendors, GND and VCC are swapped. But I don't think this is an indication. here is such a problem.

It's just an indicator...

When connected to 5 volts, only the display smokes, or does the Arduino also smoke?
