This is a Math & Automatic expansion board for micro:bit. Easy to use, and suitable for a wide range of applications. We designed this board for two sorts of application scenarios: math game and automation control. The 16 programmable touch keys and RGB LEDs on the board offers rich function and flexible input and output. Besides, the board has 1 vibration motor, 1 buzzer, 2 motor ports, 2 servo ports and 9 expansion ports, which lays a foundation for using in automation controlling application.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
- vibration motor
- A small motor with an off-centre weight on its shaft, which shakes when it spins. It matters when choosing haptic feedback, alerts, or simple movement effects, as you need to match its voltage, current draw, size, and mounting style to your project.
