Introduction

The REV Control Hub is an affordable robotics controller providing a platform for the interfaces required for building robots. The Control Hub works with the Expansion Hub and Driver Hub to create a complete robotics control system for both the classroom and the competition. These devices are most commonly used within the FIRST Tech Challenge (FTC), FIRST Global Challenge (FGC), and in the classroom for educational purposes.
