Hub 8 Pro
Powers, connects and protects a whole arm of nodes. Every port is its own USB-C power source and its own CAN segment, so one damaged cable can’t take the rest down.
Ships inside the Checkmate Leader and on its own.

P1–P8 · node ports, PD + CAN each
Machined 6061 case
A star, not a chain.
Eight node ports
Plus two accessory ports for a Sync Beacon or Contour, and an upstream port to chain hubs for bimanual stations.
Power per port
Each port is a USB-C PD source: off when empty, 20 V at 1.5 A once a node asks for it, and 3 A on up to two ports.
Isolated CAN
Every port is its own CAN segment, bridged inside the hub. A crushed cable is cut off; the others keep running.
Hardware e-stop
A two-channel input removes motor power in hardware, with no firmware in the path.
One cable to the PC, one device for every node.
The hub appears as a single USB device whose CAN channels show up as standard SocketCAN interfaces on Linux. Each node’s own USB stays reachable for setup and updates.
- CAN-FD for SmartServo G, classic CAN for SmartStepper and accessories
- Shared 20 V motor rail: one node’s braking feeds another
- Per-port power and bus telemetry
- Machined aluminum case
Power inE-stop · link · sync
Power, USB and CAN on one cable.
Every Checkmate device uses its own USB-C port as the bus. Any full-featured USB-C cable carries all three; charge-only cables won’t carry CAN.
- One cable and one Cable Clip (anodized 6061) ship in every node box; extra clips $9
- The Clip Bar 8 screws across all eight ports and clamps every cable, so a snag can’t pull a joint offline
