Unicorn HAT


What’s going to protect your beloved Raspberry Pi from an onslaught of rainbow-coloured fusion? That’s right, it’s Unicorn HAT.

Sporting a matrix of 64 (8 x 8) RGB LEDs and powered directly from the Pi, this is the most compact pocket aurora available.

Unicorn HAT provides a wash of controllable colour that is ideal for mood-lighting, 8×8 pixel art, persistence of vision effects, status indications, or just blasting colour into your surroundings.


The MagPi said that Unicorn HAT was “one of the coolest HATs around”

64 RGB LEDs (WS2812B)
LED data driven via DMA over PWM
Unicorn HAT pinout
Compatible with all 40-pin header Raspberry Pi models
Python library
Comes fully assembled
We’ve put together a Unicorn HAT Python library to make it a breeze to use, including lots of beautiful examples of what it can do.

Warning: WS2812 LEDs are bright enough to cause eye pain, do not look at them directly when brightly lit.
Photo-sensitivity warning: flashing, strobing, and patterns of lights may cause epileptic seizures. Always take care and immediately stop using if you feel unwell (dizziness, nausea, affected vision, eye twitching, disorientation).
Power: Unicorn HAT requires a >2A microUSB power supply for your Pi. We recommend this power supply.
Compatibility (audio): as Unicorn HAT uses PWM and GPIO18, it will interfere with analogue audio playback (random colour patterns and flickering). HDMI should work just fine! 😀
