Over one hundred RGB LEDs, all individually-controllable, and four tactile buttons. It's the ultimate pocket-sized rainbow generator for Raspberry Pi! Unicorn HAT Mini is a 17x7 matrix of RGB LEDs that can be controlled, both in terms of color and brightness, to display animations, text, simple images, and more. The four tactile buttons add tonnes of utility to control the color or brightness of the LEDs, or as controls for simple games, or whatever else you like.
