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.
