Description
Note:
This board has been redesigned and improved and is now available in a more compact version here.
This board provides a simple way to add motor driving capability to a BBC micro:bit. It allows two motors to be driven with full forward, reverse & stop control. It has terminal blocks to connect four input devices and a regulated 3V supply is fed in to the 80 way connector to power the inserted BBC micro:bit.
This makes it ideal for designs such as buggies (see below).
It includes an integrated Edge Connector slot for your BBC micro:bit to easily slot into. It also features external connections to the Buttons A and B inputs. This allows additional switches to be connected to the motor driver board and the state of these can then be read by the BBC micro:bit.
Get up to speed quickly. Example Microsoft TouchDevelop code and example connections in the datasheet (below).
Features:
- Drive 2 motors with full forward, reverse and stop control.
- Terminal blocks for easy connection of motors and inputs.
- 4 inputs (2 analogue inputs and 2 provide external connections to Buttons A and B as inputs).
- Includes Edge Connector for the BBC micro:bit to slot into.
- Provide regulated power to the BBC micro:bit.
Contents:
- 1 x Edge Connector Motor Driver Board for the BBC micro:bit.
Dimensions:
- Length: 67mm.
- Width: 53mm.
- Height: 18mm.

Q:
Pins 0, 8, 12 and 16 indeed CAN output PWM. So what's the fuzz about not being able to control the speed? Only pin 0 can INPUT analog values (well, also 1, 2, 3, 4 and 10). But you don't need analog input for outputting motor effects, do you?
A:
Hi Johan,
Thank you for your question. You can control speed on the motors with this board so I am a little confused by the question. We have a set of custom blocks that you can add in the blockly editor for precisely that.
It is a little difficult to code changing speed for the micro:bit because it uses a 3 channel PWM but the block code should stop that being an issue.
Best Regards
Cullen

Q:
I am trying to get my head round how the line following module works, You state in the description of the line follower that the op amp goes high for either of the outputs, but then you feed the high op amp output into INPUT1, P1 but the other other side of P1 goes to 3V doesnt that mean that both sides of INPUT1 would be 3V, surely one should be GND or am I missing something (which i think I am)
Asked by: Chris Carter
A:
Hello Chris, Input 1 or P1 isn’t linked to 3V’s, although the box use the same terminal block the two connects aren’t linked at all. The 3V’s powers the board and provides power for the BBC micro:bit, P! is an input/output pin that either sends or receives signals to the BBC micro:bit.

Q:
Do you have a CAD file for your add-on boards, so that they can be used when designing models?
Asked by: Geoff Sim
A:
Hi Geoff, We don’t currently have a CAD file for the motor driver board. We are in the process of introducing a new version so it may be once this introduction is complete a CAD file might be created.

Q:
Will your Motor Driver Board work with stepper motors?
Asked by: Barry Donaldson
A:
Although it is technically possible to do it is fairly complicated. It would be a lot easier to use the edge connector board and the motor driver breakout board, 5601-edge-connector-breakout-board 5108-kitronik-motor-stepper-motor-drive-board

Q:
Do you have a solution that can control 5 or more motors or suggestions for a work around? I have a requirement to make use of a set of robot arms that have 5 separate motors and an LED from the Micro:bit.
Thanks
Thanks
Asked by: Stephen Birch
A:
Hi Stephen, Currently the motor driver can only drive two motors, and as such we don’t have a product that can drive 5 motors.

Q:
Can you use PWM with the Kitronik Micro:bit motor board? I know that the DRV8833 driver supports PWM.
Asked by: Steve Smythe
A:
You can use PWM with Pin 0 currently, the other three pins where motors are connected can’t use PWM. We are looking into the feasibility of using all PWM pins in future versions, however this is not going to happen in the near future.
Answered by: Michael Lockhart

Q:
Is the speed of the motors controllable with PWM? The DRV8833 Datasheet suggests it should be possible.
Asked by: Charlie
A:
Currently the only pin that can be used in this way is Pin 0, so you would be able to analogue write to pin0 and set pin16 low, connecting the positive of the motor to pin0. Unfortunately you can’t analogue write to pin16, pin8 or pin12. We are looking at altering this on a new version of the motor driver board so that all four motor pins can use the PWM function.
