A USB-C to USB 3.0/2.0 hub is a compact, plug-and-play accessory designed to expand a single USB-C port (or USB-A via adapter) into multiple ports for peripherals. It typically features 1x USB 3.0 (5Gbps) for high-speed data transfer and 3x USB 2.0 (480Mbps) ports for mice, keyboards, and printers.
