A compact 1.8" TFT display with true 18-bit colour (262,144 shades) and 160 × 128 resolution. It uses a simple SPI interface requiring only 4–5 digital pins and features two white LED backlights running on 3.3 V. Driven by the ST7735R chip.
This is the raw display panel only — it is not mounted on a PCB or breakout board. Surface-mount soldering with fine-pitch techniques is required. If you need a ready-to-use version, see the 1.8" TFT breakout board with microSD card holder.
Key Features
- Resolution – 160 × 128 colour pixels
- Colour Depth – Up to 18-bit (262,144 shades)
- Driver – ST7735R
- Interface – SPI (4–5 digital pins)
- Backlight – Two white LEDs
- Operating Voltage – 3.3 V only
Ideal For
- Custom PCB designs requiring an embedded colour display
- Experienced builders comfortable with fine-pitch surface-mount soldering
- Compact projects where a breakout board is too large
Package Contents
- 1× 1.8" raw TFT display panel (ST7735R)

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
