Product Overview

Cruise-E programming car is a STEM education DIY robot platform based on micro:bit development board. Children can quickly learn micro:bit graphic programming in entertainment from easy to difficult. It can cultivate their interest in science and logical thinking, turn ideas into reality, and let them become creators. This programming car is small and lovely, using delicated metal motor, high quality battery, strong bracket, to create a compact and beautiful appearance. Most of them adopt screw connection, a small number of them use anti-plug design. Easy and safe for installation.
