This square TFT display module is made for advanced projects that need a high-resolution 4 inch panel in a compact, symmetrical format. It offers 480x480 16-bit full-colour pixels and uses an IPS display, so colour remains strong up to 80 degrees off-axis in any direction.

The display is driven by an ST7701S controller and uses both SPI and TTL RGB “dot clock” data. SPI is only used to configure the display — pixels cannot be drawn over SPI — so you will need hardware that can drive TTL RGB TFT displays directly.

This module is best suited to powerful boards such as an ESP32-S3 with octal PSRAM, or a Raspberry Pi using direct-DPI or an intermediary chip such as the ICN6211. It is not intended for everyday Feather or Arduino wiring unless your hardware specifically supports RGB-666 displays and the correct pinout.

This is the display module only; no PCB is included. Although it has a 40-pin connector, the pinout is not the same as standard rectangular 800x480 or 480x272 TFT displays.

Jargon buster

Plain-language definitions for the technical terms used above.

ESP32: ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
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 single- or quad-line connections. It provides extra working memory for tasks that exceed a microcontroller's built-in RAM, such as large frame buffers, camera or image data, audio, or sizeable data sets.
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.
RGB: Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
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.
