Yahboom super:bit expansion board
This expansion board be designed with bilateral symmetry, on board 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 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.
Feature
- 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 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.
- Compatible with LEGO bricks, can build a variety of creative shapes, such as building blocks robots, windmills, cars and so on.
- It means the BBC micro:bit can very easily become the core of a whole variety of robotics projects.

I had some issues with a V2 microbit. The hex file for V2 in the github repo didn't work - but the file downloaded from this web page does. Since it has no version or data it's not obvious to see that they are different. Please update the repo

I have try to use 5 sensor line tracking sensor for this expansion board but not working fine. It's to delayed read sensor data to control line following robot. How I can solve this issue.
Hello Friend,
Thanks for your support to Yahboom product.
Could you contact us by E-mail support@yahboom.com

I tried the Super:Bit expansion board. It was great. However, i tried the SCL and SDA (pins on the top left of Super:Bit) to the LCD 16X2 I2C module. And i connected to 5V and GND of Super:Bit at the bottom left of Super:Bit. I could not get the LCD to display "Hello World". Is there anything that i missed here?
Thanks for your 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.
Hello,
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 -
I need a schematic diagram. Is it available?
Hello friend,
Tell me your E-mail, i will send file to you. can't send here. -
Superbit is compatible with K210 Visual module?
Hello friend, K210 Visual module use serial communication, and the superbit expansion board supports serial communication. In theory, they can be connected, but we do not provide relevant tutorials.

Can I use 5V sensors and can those be powered from 5V extended interface? Do I need to place logici level converter between data lines?
Hello friend,
Sorry for late reply. There was some time difference between us, so I didn't reply to you in time.
Yes, you can use 5V sensor.
