MATEKSYS CANPDB w/ 4A BEC & JST-GH Splitter

The MATEKSYS CAN PDB combines a JST-GH CAN bus splitter with an integrated 4A BEC, streamlining DroneCAN wiring on advanced ArduPilot and PX4 builds. Fed from the main battery, it distributes CAN data and regulated 5.2 V power to daisy-chained peripherals on heavy-lift multicopters and autonomous fixed-wing UAVs.

Key features

• Combines a CAN bus expansion hub with a 5.2 V BEC, so every port carries both data and power (1 A per port).

• Supplies up to 4A continuous current via the integrated BEC to comfortably power flight controllers, servos, or auxiliary sensors.

• Utilises the industry-standard JST-GH connector ecosystem for direct DroneCAN device integration.

• Minimises wiring clutter and mitigates signal interference across large, complex airframes.
