A compact and colourful 1.8" TFT LCD breakout with a built-in microSD card slot, perfect for adding a bright display to any microcontroller project. It communicates over 4-wire SPI and includes its own pixel-addressable frame buffer, so it works with virtually any microcontroller — even those with limited memory and pins.
The display uses a genuine ST7735R TFT driver capable of full 18-bit colour (262,144 shades), delivering far better colour accuracy and refresh rates than older CSTN-type LCDs. An onboard 3.3 V regulator and 3/5 V level shifter allow the breakout to work with both 3.3 V and 5 V logic systems.

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.
- frame buffer
- A frame buffer is memory that stores a complete image before it is shown on a display. Displays without their own frame buffer need the controller to continuously send pixel data, which affects the choice of microcontroller and software library.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- 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.
- 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.
- 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.
