Add a tiny, crisp OLED to your next microcontroller project without taking up much space. This breakout carries a monochrome Blue-on-Black display that is only 64 pixels wide by 48 pixels tall, yet still has room for useful graphics, status screens and simple game interfaces.
It is easy to drive from an Arduino or other microcontroller over either SPI or I2C. The board is essentially the display section of a MicroView without the Arduino portion, giving you a compact OLED breakout for projects where you already have a controller.
The breakout provides access to 16 of the OLED’s pins. The top row of pins, GND-CS, breaks out what you need for SPI or I2C operation, while the lower pins, D7-vB, are mostly for parallel interface control. This version includes pre-soldered headers, and supporting documentation includes a schematic, Eagle files, hookup guide, design files, example code and library.
Features:
- Operating Voltage: 3.3V
- Screen Size: 64x48 pixels (0.66" Across)
- Monochrome Blue-on-Black
- SPI or I2C Interface
- Pre-soldered headers

A handy display breakout for compact instruments, diagnostics, Arduino graphics projects and small interactive builds.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- CS
- CS stands for chip select, a control pin used by SPI devices to tell which connected device should listen. It matters when you connect more than one SPI module to the same microcontroller, because each device usually needs its own CS pin.
- 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.
- 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.
- parallel interface
- A parallel interface sends several bits of data at the same time using multiple wires. It can be faster than simple serial connections, but it uses more microcontroller pins, so it is less convenient for small projects with limited wiring space.
- 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.
