The Adafruit FeatherWing OLED 128x64 adds a crisp 1.3-inch monochrome OLED display and three tactile user buttons (A, B, C) to any Feather board. The 128×64 white OLED pixel array is self-emissive — no backlight needed — delivering high contrast and excellent readability in a compact form factor.
The display uses the SH1107 driver over I2C, requiring only two data pins (plus power and ground). It includes a STEMMA QT / Qwiic connector for daisy-chaining additional I2C devices, an auto-reset circuit, and a reset button. Since I2C is a shared bus, this FeatherWing stacks with most other FeatherWings without conflict.
Key Features
- 128×64 Monochrome OLED – 1.3-inch diagonal, white pixels, high contrast, self-emissive (no backlight)
- SH1107 I2C Driver – Uses only two I2C pins; Arduino library available
- Three Tactile Buttons – Labelled A, B, and C for building a mini user interface
- STEMMA QT / Qwiic Connector – Plug-and-play I2C expansion with no soldering
- Reset Button + Auto-Reset Circuit – Built into the FeatherWing
- Universal Feather Compatibility – Tested working with all Feather boards
- Stackable – Can be stacked with other FeatherWings, including other I2C FeatherWings
Ideal For
- Adding a display and basic UI to any Feather project
- Sensor readouts, status displays, and menu interfaces
- Battery-powered projects where low display power consumption matters
Package Contents
- 1× FeatherWing OLED 128×64
- 1× Set of 0.1-inch headers (unsoldered — assembly required)

Jargon buster
Plain-language definitions for the technical terms used above.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- FeatherWing
- A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
- 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.
- 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.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
