USB Hubs

  • 1x USB 3.0+ Hub

    • The hub should support Multi-TT (MTT) if you plan to use other high-bandwidth devices along with the ESPs. Single-TT (STT) hubs may work if they are only used with ESP devices (e.g., Babble + ETVR).
    • Ensure the hub is of good quality, lightweight, compact, and has at least three ports—one for the face tracker and two for the ESP32-S3 boards.
    • Buy on Amazon

  • USB-A to USB-C Adapters

    • Make sure to have the necessary adapters if required. For instance, the Valve Index only has one USB-A port.
    • Buy on Amazon

  • 1x USB-C Cables (as short as possible) to connect both ESPs.

    • Since the ESP32-S3 uses USB-C connectors, you might need USB-C to USB-A cables, depending on your USB hub configuration.
