Introducing the Arduino UNO Mini Limited Edition: Pre-orders now open

Arduino UNO Mini Limited Edition

The iconic Arduino board is back, in the shape of the UNO Mini Limited Edition. Pre-orders have just gone live, so don’t dawdle if you want to get your hands on this stunning piece of Arduino history.

10 Million Makers Can’t Be Wrong

The UNO Mini Limited Edition is here to celebrate a pretty epic milestone in Arduino’s history. The iconic board, which first launched back in 2010, has become synonymous with Arduino itself. It’s like the company and the board are inextricably linked in the minds of makers around the world. For many, Arduino is the UNO.

There was a feature in Make: Magazine once, which declared Arduino was here to stay because it had just crossed the 10,000 sales threshold. Back then (and it’s not even that long ago), the idea that you could sell 10,000 maker boards was pretty epic. 

The UNO has now sold over 10 million units.

It’s impossible to guess how many projects that equates to. Just like us, many of you will have owned a lot of UNOs over the last decade, and some of those will have been used in multiple projects. Can you still remember your first UNO, or your first UNO project? Share them with us!

So we wanted something super cool to celebrate this new maker board milestone. And that something is the UNO Mini Limited Edition.

Meet the UNO Mini Limited Edition

First and foremost, this is an UNO like any other. It’s (almost) the same specs, with the same processor, pinouts and performance that made the UNO so popular. But there are a couple of cool tweaks we think you’ll love.

Probably one of the first things you noticed was that the USB port has been updated to USB-C. An update we’re confident you’ll appreciate, and not just because it helps with the reduced form factor. Most of us have an abundance of spare USB-C cables kicking around these days, so it’s decidedly more convenient.

And then there’s the form factor. The UNO Rev 3 is, more or less, the same size as its predecessors, dating back to the original design. As you expect, the UNO Mini Limited Edition is a quarter of the size of the original footprint, measuring 34.2mm x 26.7mm x 8mm.

Limited Edition, for Serious Collectors

It’s not just the beautiful new black and gold design that makes the board so desirable. This is a limited edition, with each board individually numbered.

All the features you’ve come to know and love are still there, so this is a fully functional UNO in every respect. But hardcore Arduino lovers will also appreciate its desirability and collectability. Everything about the UNO Mini Limited Edition screams quality, from the device to the assembly, the packaging to the printing. Who knows what an unopened UNO Mini Limited Edition (R@RE! Mint, still in box!) will be worth in the years to come.
