Inside LEGO’s 2026 Smart Brick: a sealed, sensor-packed power brick
A teardown of LEGO’s 2026 Smart Brick reveals a tightly sealed 2×4 brick packed with NFC, Bluetooth, LEDs, a microphone, and what appears to be a custom ASIC. The device houses an EM Microelectronics EM9305 BLE SoC and a 16 Mb SPI flash, with the main ASIC (DA000001-04) remaining enigmatic due to flip-chip packaging. Access requires destructive opening, and the built-in Li‑ion battery raises repairability/regulation questions in light of EU rules. Firmware analysis and open-source tooling are already advancing the reverse‑engineering effort.
