The BigTreeTech K-Hub V1.0 is a 4-port USB 2.0 hub purpose-built for Klipper 3D printer setups. It solves the common problem of needing to connect multiple USB peripherals — such as accelerometers, CAN bus adapters (U2C), webcams, and toolhead boards — to a single USB host port on an SBC like a Raspberry Pi or BTT Pi.
The hub supports dual power input: 24V from the printer's PSU or 5V USB, making it flexible for different wiring configurations. Its compact design and standard USB hub architecture ensure broad compatibility with all Klipper-supported devices. The product is priced at $17.99 making it an accessible upgrade for any multi-peripheral Klipper printer build.
Design files are published in the BigTreeTech GitHub organization. The K-Hub is especially useful in CoreXY builds with toolhead CAN boards that still require additional USB accessories on the host side.
