The Adafruit 1.44" Colour TFT LCD Display Breakout is a compact 128×128 pixel screen driven by the ST7735R controller over 4-wire SPI. Unlike older CSTN displays, this is a true TFT with full 16-bit colour and fast refresh rates, making it suitable for any microcontroller project.
The breakout includes a 3.3V regulator and 3/5V level shifter for compatibility with both 3.3V and 5V logic. A built-in microSD card slot allows loading full-colour bitmaps from FAT16/FAT32 formatted cards.
Key Features
- 128×128 Colour TFT – Full 16-bit colour with fast refresh, driven by the ST7735R controller
- 4-Wire SPI Interface – Works with any microcontroller, including low-pin-count boards
- 3.3V/5V Compatible – Onboard regulator and level shifter for flexible logic levels
- MicroSD Card Slot – Load bitmaps from FAT16/FAT32 formatted cards
- 1.44" Diagonal – Compact display size
- Open Source Library – Arduino graphics library with support for pixels, lines, shapes, text, and bitmaps
Package Contents
- 1× 1.44" 128×128 colour TFT display breakout with ST7735R driver and microSD slot
Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- 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.
- 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.
