Winstar WEO012832E display is very small; it's only 1.04", but very readable due to the high contrast of OLED display panel. The oled makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast. This 1.04 OLED module is a built-in SSD1306 IC OLED display. The module can communicate via 6800, 8080, SPI and I2C interface. The standard color for this item is yellow, but options are available in green, red, blue, white, and amber.
