Opencircuit OLED display 128 x 64 - blue - 1.3 "- I2C

This 1.3 "display is the larger version of the well-known 0.96" OLED display with the same resolution, and therefore larger, easier to read pixels. OLED (Organic Light-Emitting Diode) means that the screen consists of all small LEDs (each pixel is equal to 1 LED). As a result, the display does not need a backlight and is much more economical to use. In addition, this gives a much higher contrast, making this display very clear and legible despite its size.To set up the display, you can utilize the olikraus U8G2 library, which is installable through the Arduino IDE. Simply go to Manage Libraries, search for "U8G2," and install the latest version.However, note that boards like the Arduino Uno, Nano, or Pro Mini have limited RAM and cannot handle the "fullbuffer" examples from the U8G2 library. Instead, opt for the "pagebuffer" examples, which are more suitable for these devices.
