Super:bit Expansion Board
An expansion board that turns a micro:bit into the brain of a robot. It drives DC motors, stepper motors and servos, adds 17 IO pins for sensors, and has holes that fit LEGO Technic bricks. It works with both micro:bit V1 and V2.
Everything a micro:bit robot needs
The board has a socket for the micro:bit, a battery holder and rich onboard parts, so students can focus on building and programming.
Works with V1 and V2
Compatible with both micro:bit V1 and micro:bit V2.
Symmetrical design
A central-axis, left-right symmetrical layout that suits building-block robots and smart cars.
Rich onboard parts
micro:bit socket, programmable RGB lights, a buzzer, plus I2C and serial communication.
Strong motor drive
Drives DC motors, stepper motors and servos, along with the onboard buzzer and RGB lights.
17 IO ports
17 effective micro:bit IO ports for connecting other sensor modules.
Three power options
Micro USB, 18650 lithium battery, or a 3–5 V external battery box.
Know your board
The board is designed with bilateral symmetry. It has an onboard micro:bit socket, an 18650 rechargeable Li-ion battery socket, a USB power interface, a 3–5 V external power interface, 4 programmable RGB lights, a buzzer, an I2C interface, a WiFi camera serial port and interfaces for many kinds of motors.
It can connect 2-channel stepper motors, 4-channel DC motors and 8-channel servos, backed by a stable power scheme and several protection circuits.
Onboard components and interfaces
The board has a WiFi camera serial port, 7 anti-reverse-connection IO module interfaces, 4 I2C interfaces, 4 DC motor interfaces, 8 servo interfaces, 4 RGB lights and a buzzer, so students can finish many DIY projects.
It also brings out 17 pin header IO ports to support more sensor modules. The WiFi camera serial interface, the I2C interface and the LEGO Technic holes make it easy to grow into more interesting projects.
Three ways to power the board
Choose the supply that suits the project: a Micro USB cable (5 V, no battery needed), an 18650 lithium battery with the onboard charging circuit, or a 3–5 V external supply such as a battery box.
Safe power, longer working time
A battery socket sits in the middle of the board, so an 18650 lithium battery can be inserted directly to power it. The board has reverse-connection protection, low-voltage protection and over-current protection.
The Micro USB port supplies 5 V (max 1 A) and 3.3 V (max 0.5 A). The motor ports take their voltage from the battery.
Battery socket
The 18650 battery socket is built into the centre of the board. The battery shown in the pictures is not included with this board.
Build with bricks, drive with code
The board is compatible with LEGO Technic bricks, so students can build robots, windmills, cars and more, then control them with micro:bit programming. The board does not come with LEGO Technic parts. Pictures may show a micro:bit and building parts for illustration; they are not included.
