20x2 OLED Character Displays Description

20x2 OLED character display advantages

ST-OLEDM2002-1 is 20X2 OLED character display adaptor board that simplifies your design.The 20×2 OLED character display controller ic US2066, communicates via 6800/8080 4-bit and 8-bit parallel interface and I2C/3-wire/4-wire serial interface. Because the display 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,extremely wide viewing angle and extremely operating temperature.

The 20×2 OLED character displays are easily controlled by MCU such as 8051,PIC,AVR,ARDUINO,ARM and Raspberry Pi.It can be used in any embedded systems,industrial device,security,medical and hand-held device.
