It be designed with bilateral symmetry, onboard micro:bit board socket, 18650 battery socket, USB power supply interface, 3-5v external power interface, 4 programmable RGB lights, buzzer, I2C interface , WIFI camera serial port, all kinds of motor interfaces and so on, which is an expansion board designed for micro:bit. It also can be connected with 2 channel stepper motors, 4 channel DC motors, 8 channel servos, coupled with stable power supply scheme and various protection circuits, this expansion board has a powerful ability to drive motor. We expand 17 pin header IO ports and 10 alligator clip interfaces to support our sensor modules. The WIFI camera serial interface, IIC interface and LEGO holes make it possible for users to expand into more interesting projects. You can build your own shape with the LEGO bricks, connect some electronic devices, and control it by micro:bit programming.  It is an excellent choice for your robotic projects based on Micro:bit!


  • Central axis design, bilateral symmetry.
  • Onboard content is rich, micro:bit socket, programmable RGB lights, buzzer, and support IIC, serial communication.
  • Power ability to drive DC motors, stepper motors, servos, onboard buzzer and programmable RGB lights.
  • 17 effective micro:bit IO ports, 10 alligator clip interfaces are reserved, and some Yahboom sensor modules can be connected.
  • Three power supply method: micro USB power supply, 18650 lithium battery power supply, 3-5v external battery box power supply.
  • 6. Compatible with LEGO bricks, can build a variety of creative shapes, such as building blocks robots, windmills, cars and so on.
  • 7. It means the BBC micro:bit can very easily become the core of a whole variety of robotics projects.

Ask a Question
  • Hello, is there a way to get 5v output to motor drive on this board? I have the programmable building block Red Motor(A02) which can run 3-5v and I want higher power output from motor.

    Yes, you can get 5v output to motor drive on this board.

  • Is there a lastest version of the super:bit hex file for micropython. I’m getting 529error on my microbit after flashing the hex file.

    Thanks for your question.
    The reason for this problem is that due to the upgrade of the Microbit V2 board, there are still some problems in IIC communication.
    Now our Python library files are compatible with Microbit V2. 
    Please download new Python file on our website. Link: http://www.yahboom.net/study/Super:bit

Producto de calidad y a un precio razonable.

Best board for beginner

Easy to use and good for multi-purpose use.

It is a perfect partner for Microbit board

I bought 20 of them for programming classes last year.
The children used them to build a lot of building blocks, and controlled them through programming, knowing that there is no problem with all the expansion boards now.

I will buy another batch of Yahboom products next month.

Incredibly fun and engaging expansion board for Microbit!! I love it!

This is absolutely amazing! It is a very useful and versatile expansion board that you can spend a lot of time experimenting on.

Review of the super:bit from Philip team

Our team bought 5 expansion boards and some building block servos and motors, and plan to build some unique building block cars. Yahboom's building block motors and servos are also very good.
