OLED Breakout Board – 16-bit Color 1.27″ W/microSD Holder

We love our black and white monochrome displays but we also like to dabble with some color now and then. Our 1.27″ 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 1.27″ diagonal and contains 128×96 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). We picked this display for its excellent color, this is the nicest mini OLED we 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. Our example code shows how to read a bitmap from the uSD card and display it all via SPI.

Of course, we wouldn’t just leave you with a datasheet and a “good luck!” – we’ve 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. Check out the

tutorial

we have for both this and the 1.5″ version of the OLED for wiring diagram, code, and more!

Specifications

• 1.27″ diagonal OLED, 16-bit color
• SPI interface
• 3.3-5V logic and power
• PCB Dimensions: 35.8mm x 43mm
• Screen Dimensions: 33.8mm x 27mm
• 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.

Revision History

• As of 13th March 2023 – we are stocking an updated version of this board with a black PCB and an

  EYESPI connector

  to make cabling easier with an 18-pin FPC. We also used 

  Adafruit Pinguin

   to make a lovely silkscreen. The board is otherwise the same size, pinout, and functionality.
