VRHub

Type-C USB Hub with a host-side port

VRHub is a USB hub specifically designed for usage in standalone Virtual Reality headsets. The hub allows the headset to be equipped with additional peripherals while being tethered to a computer.

VRHub exposes 2x pads for Xiao ESP32 S3 Sense boards, allowing for integration with open-source eye and face tracking projects, such as EyeTrackVR and Project Babble. Note that we are not affiliated with either of those projects.
