HubNODE CANbus Hub (Medium)
HubNODE CANbus Hub (Medium)
Couldn't load pickup availability
Built to order. Typically ships in 3–4 weeks.
Room to grow, with power on the same harness.
Once an aircraft carries ESCs, servos, a payload and redundant sensors on CAN, the bus becomes the backbone of the airframe. The HubNODE Medium handles it two ways. Signal Only fans CAN H and CAN L out to 9 nodes. Signal + Power carries CAN H, CAN L, power and ground to 4 nodes, so each device gets data and power through one connector and one cable. Both run through a single 19-pin LEMO M-series receptacle on a potted aluminum case.
Key features
- Signal Only: 9-way CAN distribution · Signal + Power: 4-way CAN + power + ground. Each pin group is a plain common bus, so you decide which line runs on which group
- One 19-pin LEMO M-series receptacle: IP68, ratchet locking, 300 g shock and 37.8 g rms random vibration rated
- No active electronics: nothing to power, update or fail
- No built-in termination: terminate the bus at the mating connector, exactly where your architecture needs it
- Works with DroneCAN, Cyphal, CANopen, J1939 and any other CAN protocol
- Potted, green anodized aluminum case engineered to DO-160G and MIL-STD-810H environmental standards; −10 °C to +55 °C operating
- Pairs with a PowerNODE converter to feed a regulated rail to every node
- Made in our FAA-approved manufacturing facility
Typical uses: heavy-lift multicopters and VTOLs · CAN ESC and servo networks · powered DroneCAN peripherals (GPS, lights, payload controllers) · redundant sensor buses

About Node
Built like avionics, because that's what we build. Node is an avionics manufacturer holding FAA Parts Manufacturer Approval (PMA), and we've built avionics for general aviation and OEM customers for 35 years. For more than a decade we've also flown large unmanned systems: multicopters, VTOLs, helicopters and fixed-wing aircraft. Every Node Electronics part is made in our FAA-approved manufacturing facility, housed in anodized aluminum, fully potted, and engineered to DO-160G and MIL-STD-810H environmental standards, the same standards certifiable UAS autopilots are built to. It's the hardware the unmanned and optionally piloted industry needs when "good enough for a hobby build" isn't.
