## Description

Gorgeous programmable LED matrix displays with wireless connectivity and oodles of fancy extras!

Our space Unicorns are very beautiful, **all-in-one, RP2350 powered LED matrices** perfect for conveying information fabulously (or for sprucing up your desktop, makingspace or imaginarium). There's a ton of features aboard, here are some of our favourites!

**Loads\* of RGB LEDs**, all with individual colour and brightness control. Pimoroni are in mad love with these big bright squircular LEDs with their rounded apertures and built in diffusion.

**Looks great on video** - invoking RP2350 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 2 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 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?**

As of mid-December 2024, Pico Unicorns are now **Pico 2 W Aboard**! Pico 2 W and it's souped-up RP2350 chip bring some exciting improvements - including a **higher core clock speed**, **double the on-chip SRAM** and **double the on-board flash memory**. RP2350 adds hardware support for floating point number crunching, which means graphical effects and demos should run even faster!

**Which Unicorn to choose?**

All varieties of Unicorn have the same great core features: buttons, a speaker, a battery connector and an onboard Pico 2 W. However, there's now **three different shapes and sizes**, with varying amounts of LEDs. Here's a little comparison chart to make sure you get just the right amount (like mecha-Goldilocks).

### Getting Started

To make it easy to get started, all our Unicorns ship **pre-loaded with pirate brand MicroPython** and a demo reel of examples of pretty examples to stare at.

You can find more examples on Github:

- [Unicorn MicroPython firmware and examples](https://github.com/pimoroni/unicorn)

### Not your everyday RGB LEDs

In our software, we use the Pico 2 W's PIOs (Programmable IOs) to drive the LEDs. Internally, 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 make it super easy to connect up [Qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) or [STEMMA QT](https://core-electronics.com.au/catalogsearch/result/?q=stemma%20qt) 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](https://core-electronics.com.au/catalogsearch/result/?order=bestsellers&q=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](https://core-electronics.com.au/catalogsearch/result/?order=bestsellers&q=jst+sh+cable) plus a [Qw/ST to Breakout Garden adaptor](https://core-electronics.com.au/pimoroni-stemma-qt-qwiic-piicodev-to-breakout-garden-adapter.html). Want to use &gt;2 breakouts at the same time? Try [this adaptor](https://core-electronics.com.au/piicodev-splitter-1.html)!

### Notes

- Power consumption stats! We measured Galactic and Cosmic Unicorn as consuming just over 1A at maximum brightness, full white. When choosing a battery, consider that the LEDs will look their absolute best when they have access to at least 3.6V of power. At lower voltage levels you will start to see the blue elements of the LEDs fading out - this starts to become very noticeable at 2.9V and below. For best results when running on battery, we'd suggest using a chunky LiPo (check out the extras for some suggestions).
- Note that Unicorns have no battery charging hardware onboard - this is so you can use either alkaline or LiPo batteries safely. You'll need to charge up your LiPo battery with a separate battery charger (we like [LiPo Amigo](https://core-electronics.com.au/lipo-amigo-lipoliion-battery-charger-lipo-amigo.html)).
- Squircle alert! Some batches of Unicorns have LEDs with more rounded apertures (though the LED specs and brightness remain the same). They all look good, but if you want a perfectly visually matched pair (or stable) of Unicorns it's probably best to buy them at the same time.
