Frequently Asked Questions

Q: Is the 18650 battery included with the Super:bit Micro:bit expansion board?

A: No, the 18650 lithium battery is not included. The board features an on-board 18650 battery holder and charging circuit, so you will need to purchase a standard 18650 3.7V Li-ion battery separately. You can also power the board directly via a Micro USB 5V connection.

Q: Is this expansion board compatible with all versions of the BBC Micro:bit?

A: Yes, the Super:bit expansion board (KY-003) is designed to be compatible with BBC Micro:bit boards. It connects via the standard edge connector and breaks out the GPIO, power, and communication pins to convenient 2.54mm standard header interfaces for sensors, motors, and servos.

Q: Can I use Python to program robots built with this Micro:bit expansion board?

A: Absolutely. The Super:bit board is fully compatible with MicroPython programming for Micro:bit, as well as Microsoft MakeCode block-based coding. It supports 4-way DC motor control, 6-way servo control, RGB LEDs, and sensor interfaces — making it a great platform for Python-based robotics and STEM projects.

Q: What motors and servos can I connect to this board?

A: The board supports up to 4 DC motors (or 2× 5-wire stepper motors) and up to 6 servos simultaneously. This makes it suitable for building wheeled robots, robotic arms, and other multi-actuator projects with the Micro:bit.
