A 5.0-inch TFT display with 800×480 resolution, LED backlight, and a 4-wire resistive touchscreen overlay. The touchscreen adds user input capability for interactive interfaces, menus, and control panels. This is the touchscreen version of the 5.0" 40-pin TFT Display without Touchscreen.
This is a raw RGB TTL (parallel pixel-clock) display — it does not have a built-in SPI/parallel controller or onboard RAM. It requires a dedicated driver board (such as the Adafruit RA8875) or a processor with native RGB TTL output (such as BeagleBone) to drive it. Standard microcontrollers like Arduino cannot drive this display directly without a driver board.
Key Features

Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a switching power circuit that raises a lower input voltage to a higher output voltage. It is used when a device needs more voltage than its power source provides, for example running a 5 V sensor from a 3.3 V supply.
- 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.
- HMI
- HMI stands for Human-Machine Interface, meaning the screen, buttons or controls a person uses to interact with a device. Describing something as suited to HMI use suggests it is intended for user-facing applications such as control panels, dashboards or instrument displays.
- 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.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- 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.
- 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.
