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.
256 RGB LED pixels in a 16×16 matrix
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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
