This rectangular TFT module is for projects that can drive a high-pixel-count RGB TTL display directly. It provides 320x820 pixels with RGB666 16-bit full-colour output on an IPS panel, so colours stay clear at wide viewing angles.
It uses an ST7701S TFT driver. SPI is used only to configure the display; pixels are not drawn over SPI. Pixel data needs TTL RGB “dot clock” driving from a suitable host, such as an ESP32-S3 with octal PSRAM or a Raspberry Pi using direct-DPI or an intermediary chip such as the ICN6211.
This version does not have a touchscreen. The listing is for the bare display module only, with no PCB included.
Although it has a 40-pin connector, the pinout is not the same as standard rectangular 800x480 4.3 inch, 5 inch or 7 inch displays, or 480x272 4.3 inch displays, so check your driver board pinout carefully. It is not suitable for wiring directly to a typical Feather or Arduino unless your hardware specifically supports RGB-666 displays with the correct pinout.

- Technical resource: ST7701 Datasheet
A good match for advanced display projects using boards such as the Adafruit Qualia ESP32-S3 for TTL RGB-666 displays.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
- 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.
