The Unicorn HAT Mini is a compact 17×7 RGB LED matrix for Raspberry Pi, featuring 119 individually controllable LEDs and four tactile buttons. Simply pop it onto any 40-pin Raspberry Pi — no soldering required — and use the Python library to display animations, scrolling text, simple images, and mini games.
Two Holtek HT16D35A LED matrix driver chips handle all the multiplexing, giving you per-pixel colour and brightness control. The four built-in buttons are ideal for controlling display modes, adjusting brightness, or building simple interactive games.

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- 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.
