Motor:bit is a motor driving board based on micro:bit. It has integrated a TB6612 motor driving chip, which is used to drive two DC brush motors with a maximum of 1.2A on each channel. It has also integrated 12 GVS (Gnd, VCC, Signal) ports (for connecting OCTOPUS series of electric bricks) and one I2C communication port. These ports allow you to extend with various sensors and electric modules.
On the board, P3-P7, P9-P10 are IO ports for directly driving 3.3V devices; P13-P16, P19-P20(I2C port) support 3.3V/5V voltage switch. Sliding the voltage switch onboard, it is available to drive 3.3V or 5V devices. Besides, you can play music with the buzzer on the motor:bit. The motor:bit is totally designed for DIYers. You can use it to create your own smart car or more funny projects.

- Three options to choose from:
- Motor:bit itself works with both the micro:bit V1 and micro:bit V2
- Support 2 DC motors
- A motor speed controller for micro:bit
- Max driving current of single-channel is 1.2A
- Extend 14-channel IO ports and lead out it by GVS pins. Among it, 6 ports support 3V/5V voltage switch
- With 1 passive buzzer(piezo) on board
Definition of Pins:
Introduction of Major Components:
- M1-M2 Motor Connector
M1 and M2 can separately connect a DC motor with a max current of 1.2A.
- Passive Buzzer
Once a passive buzzer is connected to the P0 port on micro:bit, it can play music.
- Power Switch
Slide the switch to ON, power is connected; slide the switch to OFF, power is disconnected.
- Power Connector
The power connector is available to connect with 6-12V DC power.
- VCC Voltage Switch
Slide the switch to 5V, then VCC supply 5V power; slide the switch to 3.3V, then it provides 3.3V power. This switch is valid to 6 IO ports only: P13 / P14 / P15 / P16 / P19 / P20.
- G-VCC-S Standard GVS Port
It contains 4 (P13-P16) GPIO ports and 1 IIC communication connector (P19-P20). You can connect 3.3V/5V devices to it according to the voltage change of VCC.
- G-3V3-S Standard GVS Port
You can connect 8 devices working under the 3.3V power supply. Among them, P3, P4, P10 can be used as analog signal input connectors.
- micro:bit Golden Finger Socket
You can plug your micro:bit into this socket.
Connect two TT motors to the micro:bit as the picture shown below.
