The Klip Motor Driver for the BBC micro:bit does much more than just drive motors. It also breaks out pins 0, 1, 2, 3V and GDN (just like the main pads on the BBC micro:bit itself), and there’s a ZIP LED output as well, along with the battery voltage and another GND connection. All of these pads are designed specifically for use with crocodile clips and banana plugs. That means no soldering or fiddling with connection blocks. Also, the pads have been designed and spaced to make it difficult to short two together with crocodile clips.
It can run two DC motors simultaneously, both clockwise and counter-clockwise, and at varying speeds.
The board also features status LEDs. There are LEDs for board powered on, pins 0, 1, 2, 3 and also the two motor outputs. The motor indicator LEDs don't just monitor activity, they also indicate which direction each motor is running in, green for forwards and red for backwards. These LEDs don't just look nice, they are a great way of visually troubleshooting your code and they even allow you test your code without having to connect motors or devices to pins 0, 1, 2, 3.
Power is provided via the integrated battery supply (3 x AA, 4.5V), and the board then produces a regulated 3.3V supply which is fed into the 3V and GND connections to power the connected BBC micro:bit, removing the need to power the BBC micro:bit separately.
Note: If the BBC micro:bit is powered via its USB connector, and there are no batteries inserted, there will be no power at the 3V output connection – this is to provide some overcurrent protection for the BBC micro:bit.
