The I²C Bus Splitter allows the connection of more I²C devices by sharing the same bus. This enables sensors like the Bar30 and Celsius to be installed on the same I²C bus.

The bus splitter has several different types of connectors to allow for forwards and backwards compatibility with various sensors and autopilots. There are four DF-13 connectors, four JST-GH connectors, and through-holes for one 0.1″ header connector.

Just plug any of the eight ports into a Pixhawk or compatible autopilot’s I²C line with the provided cable and the remaining ports on the splitter will be ready to use for slave devices I²C.
