This compact white OLED gives microcontroller projects a crisp, high-contrast canvas in a very small footprint. With 128x32 pixels across a 0.91-inch diagonal, it is suited to status readouts, menus, sensor values and other small on-device displays.
The module supports both 4-wire SPI and I2C interfaces, making it flexible for a wide range of embedded designs. Its low power draw helps keep battery-powered projects running for longer.
Documentation is available in the form of a datasheet for electrical and mechanical integration details.
Specifications:
- Diagonal Size: 0.91"
- Pixel No.: 128x32
- Colour: White
- Panel Size: 30 x 8.9 x 1.2mm
- Active Area: 22.38 x 5.58mm
- Pixel Pitch: 0.175 x 0.175mm (145 PPI)
- Interface: 4-wire SPI, I2C
A handy choice for compact wearables, instruments, handheld controllers and any project that needs a small, sharp monochrome display.
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.
- 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.
- 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.
