7.0 40-pin TFT Display - 800x480 without Touchscreen

Jargon buster

Plain-language definitions for the technical terms used above.

boost converter

A boost converter is a power circuit that raises a lower input voltage to a higher output voltage. It matters here because the board can power a sensor that needs a higher supply voltage while still using a single connector for power and data.

frame buffer

A frame buffer is memory that stores a complete image before it is shown on a display. Displays without their own frame buffer need the controller to continuously send pixel data, which affects the choice of microcontroller and software library.

GPS

The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.

HDMI

HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.

HSync

Horizontal sync is a timing signal that tells a display when a new row of pixels is starting. It matters when setting up RGB TFT panels because the wrong timing can give a shifted, rolling, or blank image.

LED

A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.

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.

parallel interface

A parallel interface sends several bits of data at the same time using multiple wires. It can be faster than simple serial connections, but it uses more microcontroller pins, so it is less convenient for small projects with limited wiring space.

Pixel Clock

The pixel clock is the timing pulse that tells a display when to read each pixel’s colour data. It matters because the clock rate must match the panel’s resolution and timing requirements for the image to display correctly.

RAM

RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.

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.

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.

VSync

Vertical sync is a timing signal that tells a display when a new full screen frame is starting. It matters because RGB TFT panels often require the correct VSync timing for stable full-screen updates.
