### Connecting a Motor to the Hub
The Hub can drive up to four (4) 12V DC motors per Expansion Hub. The Hub uses a type of electrical connector known as a 2-pin JST VH connector. Currently, the FIRST-approved 12V DC motors are equipped with Anderson Powerpole connectors. An adapter cable is used to connect the Anderson Powerpole connectors to the Hub motor port.
