Maintenance
- Keep the board in a dry environment to prevent moisture damage.
- Avoid exposing the board to extreme temperatures or direct sunlight.
- Handle the board with care to prevent physical damage to components or connectors.
- When using an 18650 battery, ensure it is inserted with correct polarity. The board includes reverse connection protection, low voltage protection, and over-current protection for safety.
- Clean the board gently with a soft, dry cloth if necessary. Avoid using liquids or harsh chemicals.
Troubleshooting
- Board not powering on: Check all power connections. Ensure the Micro USB cable is functional, the 18650 battery is charged and correctly inserted, or the external power supply is providing adequate voltage.
- Micro:bit not detected: Verify that the Micro:bit board is securely seated in its socket.
- Modules/Sensors not responding: Double-check wiring connections for all modules. Ensure the correct pins are used and that your code is properly configured for the connected hardware.
- Programming issues: Ensure your programming environment (MakeCode or Python) is correctly set up and that you are using the appropriate libraries or extensions for the Superbit board. Refer to the online tutorials for guidance.
- Unexpected behavior: Review your code for logical errors. Test individual components before integrating them into a complex project.
