products description:This display module is made of 128x64 pixels, diagonal is only 1.3 inch.The controller ic SSH1106, communicates via IIC/4-wire serial interface. The power consumption is ultra low due to no backlight needed. Feature: No backlight needed, the display unit can emit light. High resolution: 128 * 64 (same as the LCD12864, but this product's sharp is more intensive). Wide voltage support: no need to modify, direct support 3.3V ~ 5V DC. The display has high contrast, extremely wide viewing angle and extremely operating temperature. Ultra low power consumption: The display makes its own light, no backlight is required, which will reduce the power required to run the OLED. So the power consumption is ultra low (far lower than TFT, LCD and other technologies).
