This compact OLED board gives your project a crisp monochrome white-on-black interface in a 1.5-inch square form factor. With 128x128 pixels and a 1:1 aspect ratio, it suits custom graphics, menus, status screens and data plotting.

The display uses Chip-on-Glass (COG) OLED technology, so each pixel emits its own light without a bulky backlight. This helps keep the module thin and power-efficient while delivering strong contrast and deep blacks compared with traditional LCDs.

For fast prototyping, the board includes two Qwiic connectors for default I2C communication, so it can be connected with a Qwiic cable without soldering or breadboarding. If your application needs faster refresh rates, standard 0.1-inch pins are broken out for SPI communication.

SPI use requires cutting traces on the back of the board and using a microcontroller with 3.3V logic. Documentation provided by SparkFun includes the schematic, KiCad files, hookup guide, datasheets and GitHub repository.

Features:

Qwiic Connect System: Two Qwiic connectors capable of I2C communication for plug-in connection with a Qwiic cable.
SPI Capable: Standard 0.1" pins are broken out for SPI communication.
Chip-on-glass OLED design eliminates the need for a backlight.
Suitable for graphics, text and data plotting.

A neat display option for Qwiic-based projects, compact instruments, handheld gadgets and embedded user interfaces.

Jargon buster

Plain-language definitions for the technical terms used above.

I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
LED: A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
microcontroller: A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
OLED: OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
PTH: Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
Qwiic: Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
SPI: A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
