What's going to protect your beloved B+ 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.
You need a good 2A power supply for your Pi for Unicorn HAT to work. We recommend the official Raspberry Pi power supply.
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! :D
Compatibility (Model B): HATs are only compatible with the newer A+ & B+ Raspberry Pi. They will not fit nicely on a B. You can hack it to work with a Model B though.
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).
