      With a little bit of thinking and understanding of electronics, this system can drive any motor or servo!!! We are absolutely stunned by its performance! on Oct 31st 2017

    2. Great Hub. Easy to use!

      A great addition to FIRST Tech Challenge. Small and compact design and very easy to use. on Sep 18th 2017

    3. Really easy and helpful

      We had a robot that we built that was waiting for power. The Mecanum wheels and motors we on, but we had not done all the power wiring. Not having to wire up two additional motor controllers to get the robot moving was a big improvement in our development time. on Jun 11th 2017
