Unicorn HAT
PIM054
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, 8x8 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"
Features
64 RGB LEDs (WS2812B)
LED data driven via DMA over PWM
Compatible with Raspberry Pi 3, 2, B+, A+, Zero, and Zero W
Python library
Comes fully assembled
Software
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.
Notes
Warning: WS2812 LEDs are bright enough to cause eye pain, do not look at them directly when
brightly lit. We recommend the use of a diffuser.
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 the
official Raspberry Pi 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! :D
