Galactic Unicorn display (Pico W on board)

64,95 €

The pride of Pimoroni, the Galactic Unicorn display with Pico W on board. With no less than 583 RGB LEDs in a 53×11 grid, you can program your own news-ticker or time display.

Also see the review in MagPi magazine:

With an appreciation of 9 out of 10, They think it is a really great product. (And we do too.) With on-board speaker, battery-connection and Pico W on board, so the display also has WiFi and thus internet connection.

How are you going to use it? As weather-display, big clock, or to pimp your desk to an ultra-futuristic look? Please let us know!   


This is what Pimoroni has to say:

A programmable 53 x 11 LED matrix / sign with wireless connectivity and oodles of extras! ????

Galactic Unicorn is a very beautiful, all-in-one, RP2040 powered LED matrix perfect for conveying information fabulously (or for sprucing up your desktop, makingspace or imaginarium). There's a ton of features aboard this one, here are some of our favourites!

???? 583 RGB LEDs lovingly arranged in a 53 x 11 grid, all with individual colour and brightness control.

???? Looks great on video - invoking RP2040 magic means we can update the LEDs really quickly (we measured around 300 fps at 14-bit precision). This means there's no nasty strobing, artifacting or brightness stepping when it's filmed, so it's perfect for adding to the background of your streaming setup.

???? 2.4GHz wireless connectivity (courtesy of the Raspberry Pi Pico W) so you can use it to display all sorts of interesting data from the internet.

There's also an onboard amp and little speaker for bleepy alerts and *futuristic noises* and a battery connector so you can power it without it having to be tethered to a USB port. Every Galactic Unicorn comes with a pair of sleek little metal legs so it can stand up on its own (and has a selection of mounting holes if you'd prefer to do something else). 

Use it to make a very fancy clock, a very fancy weather display or a very fancy output for sensors (other very fancy use cases are available).

What's new? ????

We first teased Galactic Unicorn at the Raspberry Pico W launch, but it's had quite the glow up since then. The big change is that we've switched to a new kind of LEDs that are bigger, brighter and have built in diffusion and they look absolutely *chefs kiss*. 

We've also moved the buttons onto the back for a sleeker look, added a grille in front of where the speaker sits, and made a bunch of other little changes that means the release version of GalUni is really super nice.

Kit includes

  • Galactic Unicorn (with speaker attached)
  • 2 x metal legs
  • USB A to micro-B cable


To make it easy to get started, Galactic Unicorn comes pre-loaded with MicroPython and a demo reel of examples.

If you're using C/C++ or pirate-brand MicroPython to program your Unicorn, you'll have access to our PicoGraphics library, which includes handy functions for displaying text, shapes and images. You can also control the colour and brightness of each pixel individually, of course!



Not your everyday RGB LEDs

In our software, we use the Pico W's PIOs (Programmable IOs) to drive the LEDs. Internally, Galactic Unicorn applies gamma correction to the supplied image data and updates the display with 14-bit precision resulting in extremely linear visual output - including at the low end.

The display is refreshed around 300 times per second (300fps!) allowing for rock solid stability even when being filmed, no smearing or flickering even when in motion.

Connecting Breakouts

The Qw/ST connectors on Galactic Unicorn make it super easy to connect up Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor. Want to use >2 breakouts at the same time? Try this adaptor!


  • Measurements: 330 x 78 x 10.3 mm (L x H x D, approx)
  • The 8 mounting holes are M2, 3mm in from the edge, and equally spaced 108mm horizontally and 72mm vertically. The leg holes are M2.5.
