The Raspberry Pi USB 3 Hub is designed to expand connectivity by converting a single USB-A port into four USB ports. It supports an optional external USB-C power input to supply sufficient power for high-power USB peripherals when required. For low-power devices, the hub operates reliably without external power. It has been tested for compatibility across all Raspberry Pi products to ensure stable and consistent operation. The hub is suitable for development setups, embedded systems, and educational environments.
