What's going to protect your beloved Raspberry Pi from an onslaught of
rainbow-coloured fusion? That's right, it's the 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.
* 64 RGB LEDs (WS2812B)
* Python API
* Compatible with Raspberry Pi 2, B+, and A+
* EEPROM with Raspberry Pi HAT configuration details
* LED data driven via DMA over PWM
You need a good 2A power supply for your Pi for Unicorn HAT to work.

* Warning: RGB LEDs are bright enough to cause eye pain, do not look
at them directly when brightly lit. We recommend the use of a
* Compatibility (Audio): As the HAT uses the PWM hardware and
GPIO18, it will interfere with analogue audio playback. HDMI should be
just fine though! :D
* Compatibility (Model B): HATs are only compatible with the newer
B+ Raspberry Pi. They will not fit nicely on a B. You can hack it to
work with a Model B though.
* Compatibility (Pibow): The Unicorn HAT (and other HATs) now work
just fine with our range of fine Pibows! If you have any problems
getting a hat to fit, email our support ninjas for help and advice.
* 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
Due to the way Unicorn HAT works, you can't use your Pi's analog audio
alongside it. If you see odd random colour patterns and flickering
make sure analog audio is disabled.
