DroneCAN 6-Port CAN Bus Splitter – JST-GH 4-Pin, Pixhawk Compatible

This 6-port CAN bus splitter is a compact, passive distribution board designed for expanding CAN connectivity in Pixhawk-based and DroneCAN-enabled systems. It allows multiple CAN devices such as GPS modules, ESCs, compasses, and other peripherals to be connected easily and cleanly using standard JST-GH connectors.

Built with a simple and robust design, the board ensures stable signal distribution without requiring any configuration or setup.

Pinout (All Ports Identical)

Working Principle

All ports on the splitter are internally connected in parallel for CANH, CANL, GND, and 5V lines. This enables multiple CAN nodes to share the same communication bus while simplifying wiring and installation.

No configuration is required—devices can be connected directly.

Typical Applications

• Pixhawk CAN expansion
• DroneCAN sensor networks
• UAV systems (GPS, compass, airspeed sensors)
• CAN-enabled ESC integration
• Robotics and embedded CAN systems

Important Usage Notes

• This is a passive splitter, not an active CAN hub
• Ensure proper CAN termination (120Ω at both ends of the bus)
• Use only one 5V power source on the network to avoid backfeeding
• Keep cable lengths short for optimal performance

Package Contents

• 1 × 6-Port CAN Bus Splitter Board
