Holybro CAN Hub - 27cm
by Holybro

The Holybro CAN Hub Module (27cm Cable) is a professional-grade, powered CAN bus expansion solution designed for enterprise sUAS, industrial multirotors, and complex autonomous drone ecosystems. When building advanced aircraft equipped with multiple peripherals—such as DroneCAN GPS units, digital compasses, smart batteries, rangefinders, and specialized payloads—a single CAN port on a flight controller quickly becomes a bottleneck. The Holybro CAN Hub addresses this limitation by adapting a single CAN bus input into four independent, highly reliable connection ports, ensuring seamless and streamlined component integration.

Unlike passive hubs that draw raw power directly from the flight controller's rail, this intelligent module features an integrated step-down power supply. While standard flight controller CAN outputs are easily dragged down by multiple peripherals (often dropping below 5V due to shared electrical loads), this module hooks directly to your main power distribution system with a wide 2S to 12S LiPo input voltage tolerance. Backed by its own dedicated hardware regulators, the hub outputs a rock-solid, isolated 5.2V power supply to each peripheral. It safely provides up to 1.0A per port with a 3A total combined threshold, shielding your flight controller from overcurrent situations and ensuring absolute telemetry link safety during critical flight operations.
