Creative Robotics Kit for micro:bit
The Creative Robotics Kit for micro: bit is an advanced robot construction platform with micro: bit as its core, integrating key components such as desktop robot chassis, exclusive micro: bit expansion board, high-performance servos, precise tracking sensors, and ultrasonic sensors. The top plate design is clever and can perfectly adapt to 9g metal servos, and is equipped with convenient sensor fixing holes, greatly simplifying the installation process of ultrasonic sensors, expansion boards, and other sensors.
Its IO expansion board is powerful, equipped with 10 flexible digital/analog 3Pin interfaces and 3 efficient IIC interfaces, providing users with a vast space for device expansion and control. It is worth mentioning that the expansion board is equipped with dual motor drivers, effectively releasing the pin resources of the micro: bit. In addition, the expansion board cleverly introduces the micro: bit's gold finger interface (covering 0, 1, 2, 3V, GND), further enriching developers' interface options and enhancing project flexibility and creativity.
