At CES 2026 in Las Vegas, Lego pulled the wraps off a familiar-looking product that behaves like a small computer. The new Smart Play platform centers on a standard 2x4 LEGO brick that packs processing, sensing, audio, wireless networking, and charging into a form factor that can still snap into a model. Tied to a March 1 retail launch, the Smart Brick debuts in three Star Wars sets, with pre-orders opening January 9.
Under the plastic, Lego has built what is effectively a mixed-signal embedded system. The company says the core is a custom 4.1mm ASIC with integrated sensors, RGB LEDs, a tiny speaker, and a radio stack. Power comes from an internal rechargeable battery that charges inductively, designed so the brick can be topped up even when buried inside a build.
