PiMoroni Unicorn Hat
The PiMoroni Unicorn Hat is an 8×8 array of super-bright LEDs. It is ideal for mood-lighting, 8×8 pixel art, persistence of vision effects, status indications, or just blasting colour into your surroundings. It is compatible with Raspberry Pi 2, B+, and A+, has a Python API and plugs straight onto the GPIO pins.
Available on backorder
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, 8×8 pixel art, persistence of vision effects, status indications, or just blasting colour into your surroundings.

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 diffuser.
- Compatibility (Audio): As the HAT uses the PWM hardware and GPIO18, it will interfere with analogue audio playback. HDMI should be just fine though! 😀
- Compatibility (Model B): HATs are only compatible with the newer B+ and Model 2 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 twitching, disorientation).
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.
