This RGB LED HAT adds a 4×8 matrix of individually addressable RGB LEDs to your Raspberry Pi. With 256 brightness levels and 24-bit colour depth (over 16.7 million colours), it's perfect for creating colourful displays, status indicators, and visual effects controlled by a single data pin.
The HAT plugs directly onto any Raspberry Pi with a 40-pin GPIO header. Control pins are also broken out for use with other microcontrollers.

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.
- DIN
- DIN means data in, the pin where this display receives data from the controller. Connecting DIN to the correct SPI data output pin is needed for the screen to receive pixel and command information.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- 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.
- 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.
