This square TFT module is for advanced display projects that need a high-resolution, 3.4 inch IPS panel with a 480 x 480 pixel layout. It delivers 16-bit full-colour output and wide off-axis viewing, making it a neat fit for compact dashboards, controls and custom embedded interfaces.
The display uses an ST7701S driver with SPI for display configuration and TTL RGB “dot clock” data for the actual pixel output. You cannot draw pixels over SPI, so it needs hardware that can drive RGB-666 displays directly, such as a suitable ESP32-S3 setup with octal PSRAM or a Raspberry Pi using direct DPI or an intermediary chip such as the ICN6211.
This version does not include a touchscreen, and it is supplied as the display module only — no PCB is included. Although it has a 40-pin connector, it does not share the pinout used by common rectangular 800 x 480 or 480 x 272 TFT displays, so check compatibility carefully before designing it in.
Specifications:
- Display size: 3.4"
- Resolution: 480x480
- Colour depth: 16-bit full-color pixels
- Display type: IPS display
- Viewing angle: up to 80 degrees off-axis in any direction
- Touchscreen: No touchscreen
- TFT driver: ST7701S
- Interfaces: SPI and TTL RGB 'dot clock' data
- SPI function: only for configuring the display - you cannot draw pixels over SPI
- Connector: 40-pin connector
- Pinout compatibility: does not have the same pinout as standard 'rectangular' 800x480 (4.3", 5" or 7") or 480x272 (4.3") displays
- Required host support: RGB-666 displays
- Included: just the display module
- PCB included: No PCB is included

Best suited to experienced makers and product developers, this panel pairs well with driver hardware designed specifically for TTL RGB-666 displays, such as the Adafruit Qualia ESP32-S3 for TTL RGB-666 Display.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- IPS
- IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.
- octal PSRAM
- Octal PSRAM is external pseudo-static RAM that uses an eight-line data interface for higher bandwidth than simpler memory connections. It matters for display projects because large screens and animations can need more working memory than the microcontroller has built in.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- RGB-666
- A parallel display colour interface that sends 6 bits each for red, green and blue, using many pins to stream pixel data to a screen. It matters because RGB-666 panels need a driver board with the right connector, timing signals, and software setup, rather than the simpler wiring used by small SPI displays.
- 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.
