  • The mini and smart OLED display is of strong readability due to its high contrast.

  • The display does not require backlight self-illumination, it lowers the power for the OLED display to work.

  • The loaded voltage regulator and the built-in boost converter made it possible to connect the power in 5V. It is easy to connect to the mini controller in 3V/5V power without any level translator.
