OLED & Controller
The integrated built-in controller used by this OLED is SSD1309, which has 128 × 64 bits SRAM, supports up to 128 x 64 pixel screen, supports SPI/I2C/ 6800 parallel port/8080 parallel port, 256-level brightness settings, this screen is 128 × 64 pixels, so the internal SRAM is not fully used.
This module adopts four-wire SPI and I2C interfaces, with good compatibility and high transmission speed.

FAQ
1. 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, and the OLED will not light up.Program control is required to brighten the OLED.
2. 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, or there will be afterimages and cause damage to the OLED.
