More Information
The ELECFREAKS 32 IN 1 micro Wonder Building Kit combines construction, electronics and coding through 32 guided projects.

Learners can build models such as a robot arm, motorcycle, rotary chairs, aerial ladder truck and drawing machine. ELECFREAKS’ online wiki provides project resources to help students assemble and program their creations before developing their own designs.
The kit uses the Wukong expansion board, with a built-in rechargeable lithium battery and connections supporting up to eight servos and two DC motors. This is the board’s expansion capacity, rather than the number supplied.
Included sensors cover line tracking, ultrasonic distance detection with Sonar, and water level detection, allowing students to explore how models respond to their surroundings.
With MakeCode and Python support, the kit suits classroom STEM activities, coding clubs and individual or group projects.
A micro:bit board is required and sold separately.
