Adafruit love Adafruit's black and white monochrome displays but They also like to dabble with some color now and then. Adafruit's big 1.5" color OLED displays are perfect when you need a small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 1.5" diagonal and contains 128x128 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). they picked this display for its excellent color, this is the nicest mini OLED Adafruit could find!
This OLED uses the SSD1351 driver chip, which manages the display. You can talk to the driver chip using 4-wire write-only SPI (clock, data, chip select, data/command and an optional reset pin). Included on the fully assembled breakout is the OLED display and a small boost converter (required for providing 12V to the OLED) and a microSD card holder. This design includes built-in logic level shifting so you can use it with 3-5VDC power and logic levels. Adafruit's example code shows how to read a bitmap from the uSD card and display it all via SPI.
Of course, Adafruit wouldn't just leave you with a datasheet and a "good luck!" - Adafruit have written a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code. The code is written for Arduino but can be easily ported to your favorite microcontroller! we do not have a detailed wiring tutorial at this time, but if you follow the example code wiring it should work just fine.

- Display current draw is completely dependent on your usage: each OLED LED draws current when on so the more pixels you have lit, the more current is used. They tend to draw ~30mA or so in practice but for precise numbers you must measure the current in your usage circuit. This does not include the SD card, which is separate
