Take your micro:bit robotics builds to the next level with the Kitronik All-in-one Robotics Board. This all-in-one control solution lets the BBC micro:bit drive up to 4 motors (or 2 stepper motors) and 8 servos, making it the perfect foundation for a wide variety of robotics projects.
The board features 2 Dual H-Bridge Motor Driver ICs and 8 servo outputs (standard and continuous rotation), all controlled via I2C through a 16-channel driver IC. With 17 additional I/O expansion points and broken-out I2C lines, you can easily add sensors, ZIP LEDs, and other I2C-compatible devices.
Key Features
- 4 Motor Outputs – Drive 4 standard motors or 2 stepper motors via dual H-Bridge Motor Driver ICs
- 8 Servo Outputs – Supports both standard and continuous rotation servos
- 17 I/O Expansion Points – All usable micro:bit pins broken out to a 2.54mm pitch link header for easy soldering
- I2C Breakout – Pins 19 & 20 broken out for connecting additional I2C-compatible devices
- Flexible Power Input – Power via terminal block or servo-style connector; regulated 3.3V supply powers the micro:bit directly
- No Separate Power Needed – The board supplies regulated 3.3V to the connected micro:bit and external devices via the link header

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
