Lego unveils new smart brick with embedded computer inside — Smart Play platform features tiny 4.1mm custom ASIC with sensors, RGB LEDs, and even a tiny speaker

Lego has introduced a new Smart Play platform featuring a small computer embedded inside a standard 2x4 LEGO brick. The brick includes a custom 4.1mm ASIC with sensors, RGB LEDs, a tiny speaker, and a radio stack, all powered by an internal rechargeable battery. Using near-field magnetic sensing and Smart Tags, the brick can understand its surroundings and communicate wirelessly with other bricks through BrickNet. The Smart Brick is designed to generate sound effects in real time and trigger interactive behaviors in models without the need for a camera, voice recording, or cloud-dependent AI. This compact and self-sufficient computer is a unique addition to Lego's lineup, offering interactive features without requiring a separate device.
