Inherits the special features of the 9g motor while improving torque and speed at the same time.

* Uses an axle connector for output
  * Allows connecting axles of different lengths to better suit your needs
* Dual Outputs
  * Output axles are found on both sides
* Larger rotational range
  * Has a full 360° range
* Higher Torque
  * About 3 times the torque of a 9g motor

### Connection

#### Armourbit

***

Connect the motor to the motor ports on the Armourbit.

```
Reversing the connection would not damage the motor, but the rotational direction will be reversed.
```

#### Robotbit

***

Connect the motor to the motor ports on the Robotbit.

### FAQ

1: The Micro:bit does not react when I click the programming blocks.

Make sure the Micro:bit has been connected to the Kittenblock and then try flashing the firmware.
