FAQ 1. Question:Why does the OLED module not turn on when it is connected to the power supply?
Answer: OLED does not have a backlight, and the display is self-illuminating. Only connect VCC and GND, the OLED will not light up. Program control is required to brighten the OLED.

2. Question:What should I pay attention to when using this OLED module?
Answer: 1. Be careful not to connect the power supply in reverse.
2. The same picture cannot be displayed for a long time, otherwise it will produce afterimages and cause damage to the OLED.
