Dimensions

In Lego units:

  • Length: 10

  • Width: 5

  • Height: 3

  • Output Axle: Technic Axle

In mm units:

  • Length: 72mm

  • Width: 39mm

Connection

In this demonstration, Robotbit is used. It is also possible to use an Armourbit.

Robotbit

Connect the cable to the motor.

Then connect the motor cable to the motor ports of the Robotbit.

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