The REV Robotics Expansion Hub is an affordable hardware controller which can communicate with any computer, including Android tablets/phones and the REV Robotics Control Hub. The Expansion Hub is loaded with hardware interface options to enable driving motors and servos, interfacing with sensors, and communicating with other devices via several protocol options.  

The Expansion Hub incorporates ESD and reverse polarity protection and is purpose built to stand up to the rigors of use in the classroom or on the competition field. 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. 

Expansion Hub Warranty and Repairs

We strongly recommend reviewing the REV Robotics Warranty and Returns Policy, including the Expansion Hub Repair portion. Please contact if you suspect your Expansion Hub is in need of repair.

REV Hub Interface Software

The REV Hub Interface is a beta piece of software which allows for direct connection to your REV Expansion Hub and its peripherals from your Windows PC.

This interface provides a method for teams to prototype with motors, servos, and sensors in a way that is faster and easier than setting up an entire robot control system. It is also a valuable troubleshooting tool that can help isolate the cause of an issue and determine if it is electrical or software related. The Expansion Hub firmware can also be updated through this interface in addition to the Robot Controller Application.
