Yes it is! The motor on your Marbel 2.0 is equipped with a waterproof plug-and-play connector, so there is no soldering required and no need for running wires.
When engineering the Marbel 2.0 we focused on designing components to be self-serviceable and even upgradeable. As a result, almost everything can be serviced by the user and even replaced in a matter of minutes. In addition, several of the Marbel 2.0 parts are backwards compatible with the Original Marbel Board.
