Clear screens are no longer a thing of the Sci-Fi world! The Qwiic Transparent OLED HUD is SparkFun's answer to all of your futuristic transparent HUD needs. Designed for use in vehicle heads-up displays, this OLED panel is brilliant in the dark but easily visible in daylight. The display is "area colored" meaning that while no one segment can change colors, there are different colored segments on the display. 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. Any controller with larger RAM should have no problem. It has been tested to run very well on an Arduino Mega 2560. In addition, your 3.3v source should be robust enough to supply around 400mA to the display.
