Engineered in Elgin, IL USA, the Color OLED Arduino Shields are available as three models: 1.27”, 1.5” and 1.69” diagonal. Each Color OLED Arduino Shield comes with a serial interface color OLED display module. These shields are not limited to just the Arduino brand boards; with the single row pin-out, they can easily be breadboarded to any existing development board. These shields also come 3.3 V - 5 V ready in order to support a broader range of end products. Since the Arduino Development boards are powerful tools, a micro SD slot comes as a built-in standard for the Color OLED shield allowing additional storage space for more complex code. This eliminates any memory constraints of the Arduino board.
