In addition to the built in protections, the Hub also features keyed and locking connectors to prevent connection problems in the heat of competition and is fully field upgradable so your hardware can always run the most up-to-date firmware.

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. Vince Westin, FTC Mentor on Jun 11th 2017
