Unicorn HAT HD crams 256 RGB LEDs, in a 16×16 matrix, onto a single HAT. High-definition rainbow goodness!
You can still use it for all of the same things as the regular Unicorn HAT, but with four times as many pixels it makes much more complex animations possible, including scrolling text, and even low resolution videos.
The bundled ninja diffuser makes the pixels look extra shiny by providing some subtle diffusion, blurring the lines between each pixel. Simply use four of the nuts to space the diffuser slightly away from the HAT, and the other four to secure it.

Pixels driven by ARM STM32F and three STP16CPC26 LED drivers
The ARM chip on Unicorn HAT HD does all of the heavy lifting, meaning that you can just bung data to it, and it’ll take care of the rest. It acts as the agent between your Pi and the three STP16CPC26 LED drivers that actually drive the LEDs.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
