Product description: OLED display blue 0.91'' 128 x 32 px I2C - Qwiic - SparkFun LCD-24606
SparkFun OLED display with a diagonal of 0.91'' and a resolution of 128 x 32 px , which is ideal for small, compact electronic projects. The use of OLED technology allows for a clear image without the need for backlighting, which translates into lower power consumption and a thinner profile compared to traditional LCD screens. Thanks to the built-in I2C interface, communication with microcontrollers (e.g. ESP32, Arduino, STM32) is quick and easy. The display is part of the Qwiic ecosystem - an integrated connection system for sensors, actuators and other modules, which allows for quick prototyping without the need for soldering. The use of vertical Qwiic connectors allows for easy installation in the housing , and the optimized display firmware updates only the changed areas of the image, which additionally speeds up its operation.
The manufacturer has prepared a detailed user guide that makes it easier to get started with the display.
OLED display blue 0.91'' 128 x 32 px I2C - Qwiic - SparkFun LCD-24606.

SparkFun Display Programming
The display is supported by a dedicated SparkFun Qwiic OLED Arduino Library , available in the Arduino environment . This library offers a rich set of graphic functions, such as drawing pixels, lines, rectangles, circles, and displaying texts and bitmaps. The library is optimized to quickly process only those areas of the screen that have changed, which ensures high performance and memory savings.
Qwiic System
Qwiic Connect System is an ecosystem that simplifies the prototyping process by eliminating the need for soldering . With a common 4-pin connector with a 1 mm pitch, Qwiic enables fast and error-free connection of components. The connectors are polarized, which prevents incorrect connection of devices .
The display uses I2C communication.
The image is monochrome, blue on a black background.
Display Applications
- IoT projects : thanks to its compact design and low power consumption, ideal for displaying the status of devices.
- Watches and status displays : thanks to its simple integration with microprocessor systems, it can be used to display times, notifications or system parameters.
- User interfaces : The ability to display four lines of text makes it suitable for creating simple control interfaces on small devices.
