USB Subsystem

The Intel Joule expansion board has three physical USB connectors:

  • J7 – USB 3.0; Type-C connector
  • J6 – USB 3.0, Type A connector for a hub or single input device
  • J9 – Micro USB connector dedicated to serial debug. See Debug and Troubleshooting for more information.

Refer to Expansion Board Interfaces for the locations of these connectors.

See USB Type-C Power Input (J7) for options to use USB Type-C to power the expansion board.
