This document describes how to connect and configure two Expansion Hubs for use in the FIRST Tech Challenge. Note that the FIRST Tech Challenge Game Manual Part 1 (rule \<RE07\>, part f) limits the maximum number of Expansion Hubs on a single robot to two.
**Important Note:** This document describes the process for setting up a smartphone Robot Controller with two Expansion Hubs. The process is similar if you want to connect a Control Hub (which has its own built-in Expansion Hub) to another Expansion Hub.

Use this process to check the serial addresses for each of your Expansion Hubs.
**Important Note:** By default, a REV Robotics Expansion Hub should have its address preset at the factory to a value of 2. Also by default, a REV Robotics Control Hub should have the address for its internal Expansion Hub preset at the factory to a value of 1. If you are using a Control Hub combined with a second Expansion Hub, then their factory addresses (1 and 2 respectively) should not conflict. You should not need to change either address for this combination.
**Important Note:** An address of 1 is typically reserved for a Control Hub. As a general rule, you should avoid using an Expansion Hub with an address of 1. Your Expansion Hubs should all have non-conflicting addresses that are also not equal to 1.
### Changing the Address of an Expansion Hub
You can use the Advanced Settings menu of the FTC Robot Controller App to change the address of an Expansion Hub. Note that it is recommended that when you change the address of an Expansion Hub, you only connect one Expansion Hub to the Robot Controller during the change address process.
