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 power circuit that raises a lower input voltage to a higher output voltage. It matters here because the board can power a sensor that needs a higher supply voltage while still using a single connector for power and data.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine 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 memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can 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, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- 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.
