A 1.5" colour OLED breakout with 128×128 RGB pixels and 16-bit colour depth, driven by the SSD1351 controller. Because it uses OLED technology, there is no backlight — blacks are truly black with excellent contrast. The fully assembled breakout includes a built-in boost converter (12V for the OLED), microSD card holder, and logic level shifting for 3–5V power and logic.
Communicates via 4-wire write-only SPI (clock, data, chip select, data/command, and optional reset). The included microSD holder allows loading bitmaps from a card for display.

Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a switching power circuit that raises a lower input voltage to a higher output voltage. It is used when a device needs more voltage than its power source provides, for example running a 5 V sensor from a 3.3 V supply.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- microSD card
- A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.
- 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.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- 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.
