### Geekservo Features

* Clutch Protection:
  * In case of violent turning of the output axle, the clutch is enabled to protect the gears from damage.
* Flexible Installation:
  * Can be mounted on standard Lego bricks or with Technic elements, providing a lot of possibilities for installation.
* Small and lightweight:
  * Suitable for small robotic projects.

### 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.
