Pimoroni Pimoroni Pico Unicorn Pack
We've resized our familiar Unicorn setup so that it fits nicely on the back of your Pico - with a tidy 7x16 matrix (that's 112 RGB LEDs!) it's surely the fanciest backpack going. The four tactile buttons can be used to switch between modes, as controls for simple games, or adjusting brightness.
