The EYESPI Breakout Board brings the 18-pin EYESPI FPC connector out to standard 0.1"-spaced headers, making it easy to breadboard and prototype with EYESPI-compatible displays. Each pin is clearly labelled, and for most display projects you only need the left half of the header for power and SPI connectivity.
The EYESPI standard is a consistent connector and pinout across a range of TFT and E-Ink display breakouts — look for the EYESPI logo on the back of compatible displays.

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.
- FPC
- FPC stands for flexible printed circuit, a flat flexible cable or connector style often used where space is tight. It matters because this breakout needs the correct pin count and pitch FPC cable to connect reliably to the display or high-speed interface.
- 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.
- 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.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
