Overview
The Yahboom Super:bit 2.0 is a multi-function expansion board for BBC micro:bit, designed with a central-axis symmetrical layout and building-block mounting holes for robotics and STEM projects. It integrates a micro:bit board socket, motor/servo drive interfaces, sensor expansion ports, onboard RGB lights and buzzer, plus multiple power-supply options including an 18650 battery socket and Micro USB power.
Key Features
- Central-axis symmetrical design for convenient model building (e.g., building-block car and bionic robot structures).
- Multi-channel drive capability: 4-channel independent motor control and 8-channel servo control.
- Onboard devices: 4 programmable RGB lights and passive buzzer.
- Expansion connectivity: 17-pin DuPont line IO ports and multiple PH2.0 module interfaces (including I2C and serial).
- Multiple power supply methods: Micro USB power supply port, 18650 lithium battery power supply (with onboard charging circuit), and 3–5V external power supply port (example shown with 2x AAA battery box).
- Protection scheme listed: reverse connection protection, low voltage protection, and over current protection.
- Programming support shown: MakeCode graphical programming and Python programming.

Details
Super:bit 2.0 turns a BBC micro:bit into a practical robotics controller with motor, servo, and sensor connections.
The central-axis layout and mounting holes make it easy to integrate into building-block style cars and robot frames.
PH2.0 module ports simplify sensor add-ons like distance, light, temperature, and other classroom modules.
Drive multiple actuators at once—up to four DC motors and eight servos for more complex micro:bit projects.
BBC micro:bit is required and sold separately.
Power projects with an 18650 cell using the onboard holder and protection features for stable operation.
Choose Micro USB, an 18650 rechargeable battery, or a 3–5V external supply depending on your build.
Start quickly with MakeCode blocks, then move to Python when you’re ready for text-based control.
Step-by-step tutorials and sample code help with first-time setup, expansions, and sensor experiments.
Backed by online technical support and a development team for troubleshooting and project guidance.
Clear top and bottom views help you verify connectors, mounting holes, and overall board size before buying.
