The future is here! The SparkFun Qwiic Transparent Graphical OLED Breakout allows you to display custom images on a transparent screen using either SPI or I2C connections. Brilliantly lit in the dark and still visible by daylight, this OLED sports a display area of 128×64 pixels, 128×56 of which are completely transparent. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system making it easy to get started with your own images. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.
The Arduino sketch required to drive this display requires quite a bit of dynamic memory, meaning that it is not going to fit on a smaller controller like an ATmega328. Control of the OLED is based on our new HyperDisplay library and any controller with larger RAM should have no problem. In addition, your 3.3V source should be robust enough to supply around 400mA to the display.
**Note:** The I2C address of the Graphical OLED is 0x3C and is jumper selectable to 0x3D. A multiplexer/Mux is required to communicate to multiple Graphical OLED sensors on a single bus. If you need to use more than one Graphical OLED sensor consider using the [Qwiic Mux Breakout](https://www.sparkfun.com/products/16784).
*The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.*
