SparkFun Qwiic OLED Display (0.91 in., 128x32)

This 0.91-inch monochrome OLED uses smart I2C updates to keep your microcontroller running fast, displaying up to four lines of crisp blue text on a black background.


Description

Pack 128x32 individual OLED pixels into a tiny 0.91-inch diagonal frame with the SparkFun Qwiic OLED Display! This display board comfortably displays up to four lines of text or custom monochrome graphics, providing an incredibly clear readout for your custom electronics.

Because the SparkFun Qwiic OLED Display uses OLED technology, there is no bulky backlight layer. Giving you a significantly thinner profile, exceptionally high contrast (blue on a deep black background), and a fraction of the power consumption compared to traditional LCDs.

Smart Updating for Fast Performance

The Qwiic OLED Display's firmware uses intelligent update techniques (similar to "Dirty Rectangles" or "Bit blit" computer graphics operations) to refresh only the pixels that have changed. This drastically reduces the data sent over the I2C line and keeps your main processor free to handle other critical tasks.

Redesigned for Easy Installations

This V1.1 revision introduces physical updates designed specifically to make enclosure mounting hassle-free.

  • Concealed Wiring: We've moved both Qwiic connectors to the back of the board and oriented them vertically. This allows you to route cables directly behind the display and keep them hidden inside your enclosure.
  • Simplified Mounting: The two mounting holes have been relocated to one side for a more stable installation point for 3D printed cases or custom panels.

Whether you are building a custom sensor readout, a compact user interface, or anything in between, this display offers the visual clarity and straightforward hardware integration you'll need for your next project!
