Micro:bit 32-in-1 Wonder Building Kit

The ELECFREAKS Wonder Building Kit for micro:bit is an educational construction and programming set designed for children, students, and beginners learning coding and electronics. Combining over 400 LEGO®-compatible building blocks, multiple sensors, and the Wukong expansion board, the kit enables the creation of 32 guided projects, including robotic arms, smart vehicles, and interactive systems.

The kit supports both Microsoft MakeCode and Python, allowing users to start with block-based programming and progress to text-based coding. A built-in rechargeable Li-ion battery enables fully wireless operation, making the set suitable for classrooms, workshops, and home learning environments.

Thanks to Grove-compatible sensor ports, the system can be easily expanded with additional modules. The Wonder Building Kit is compatible with micro:bit V1 and V2 (micro:bit not included).
