Lego announces the Smart Brick, the “most significant development” in 50 years

On March 1, 2026, the Lego Group will begin selling the most ambitious building block it has ever made: a mini-computer that fits entirely inside a classic 2×4 Lego brick. When you spot NFC-equipped smart tags nearby, embedded inside new Lego tiles and new Lego minifigures, or when you see other smart bricks, the company claims they’ll bring entire Lego sets to life — from the whirring of lightsabers, rumbling engines, light-up blasters, and Lego Star Wars music.

The “Smart Brick” and “Smart Toys” initiatives, just announced at CES 2026, are nothing like the “Smart Brick” initiative. Mega Lego Mario games This requires two AAA batteries and is mostly only activated when the bottom-mounted cameras detect color or barcodes. It charges wirelessly, with a pad that can charge several bricks at once, and a battery that “will still work after years of inactivity.”

They have light, sound, and light sensors, and inertial sensors to detect motion, tilt, and gestures, and they form a Bluetooth network with other smart bricks, so they’re aware of each other’s location and orientation — so Lego Star Wars ships and figures can do battle, for example, or so Imperial march It plays when Emperor Palpatine sits on his throne. When integrated into LEGO cars, the bricks can detect which one crosses the finish line first, or change from engine noise to sound effects if the car rolls over. The computer inside is a custom ASIC smaller than a single Lego stud and the firmware can be updated via a smartphone app.

The bricks also have a microphone, one that Lego Group spokeswoman Jessica Benson explained is used as a virtual button rather than recording anything. “I’ve seen it where you blow on it, if you put it on a birthday cake, for example, it makes things happen. It’s used a lot as another sensor point, it doesn’t record any details, it just picks up that audio-related input and reacts in real time to what the kids do with it.”

Benson also confirms that there is no AI in this product at all, and no camera. (Without a camera to scan barcodes, it is not compatible with Lego Mario tiles.)

The first sets to ship on March 1st will be Lego Star Wars:

Measures approximately 4 x 4 x 5.5 inches (10 x 11 x 15 cm) for the TIE Fighter and 2 x 8.5 x 7.5 inches (6 x 22 x 19 cm) for the X-Wing Included Small Outpost Buildings These are a bit smaller than the “regular miniature scale” Lego Star Wars ships we’ve gotten in the past – Smart Bricks add to the cost, as you’d expect.

If all you got for that money was replacing the imaginary lasers and buzzing sounds kids can already make with their mouths, that would be one thing — but there’s enough technology here that it could be much more than that. Lego spokesman Jack Rankin points out that the tags can lead to more creative forms of mixed-up play, too — when kids tried out an early smart tag that made a duck sound and combined it with a helicopter set, they enjoyed owning a duck helicopter, too.

It’s highly unlikely that they’ll stop at just a few Lego Star Wars sets. The Lego Group describes the new computer parts as “the most significant development in the Lego System-in-Play since the introduction of the Lego Minifigure in 1978”, and there are unconfirmed rumors that Upcoming Lego Pokémon sets Next would be to get them. Company They’re already quietly piloting them in 2024 In the Lego City set too.

“Lego Smart Play will continue to expand through updates, launches and new technology,” the company writes.

It’s definitely not A computer brick I asked Lego to make – But I’m looking very We look forward to trying it out this week at CES.
