DSD TECH 0.91 0.96 1.3 INCH IIC OLED LCD Screen Support U8glib for Arduino AVR

0.96 inch (128*64)

1.3 inch (128*64)

0.91 inch(128*32)

Features

• 0.96 INCH OLED Screen: Resolution is 128*64,Very Clear,Black background with blue text display.
• IIC(I2C) interface: Only 4 PIN( VCC, GND, SCL, SDA), Simpler than SPI interface Screen, you can leave more ports for connecting other sensors.
• Sample Code and Technical Support: You can drive this display through the u8glib library. DSD TECH also provides complete sample code and instruction manuals. you can drive this OLED screen in half an hour,
• The main chip is SSD1306; supports DC 3.3V to 5.0V supply. Working Temperature: -30 degrees ~ 70 degrees

Arduino Uno OLED Wiring

The image below shows how to connect the Geekcreit 0.96 inch OLED I2C display to Arduino. Pin connections are as follows for wiring the OLED display to an Arduino Uno.

• OLED GND – Arduino GND
• OLED VCC – Arduino 5V
• OLED SCL – Arduino Uno A5
• OLED SDA – Arduino Uno A4

Install "u8glib" 

You can install “u8glib” via library management of Arduino IDE.

  or you can download library from :  https://github.com/olikraus/u8glib
