Can Pixhawx do additional data communication function?

Hi guys,

I’m a beginner of Ardupilot. I’m planning to build a rover that can measure the illuminance values automatically according to the pre-defined points. But I’m struggling with how can I build the communication between the Pixhawx controller and the illuminance meter. Does anyone have this kind of experience before? Any suggestions will be appreciated

It will route / forward Mavlink packects between the devices you may have and/or gcs

this could actually be quite useful. MAVLink is the usual protocol to communicate with external devices that have a microprocessor of some kind, but device drivers can use any of a number of serial protocols, CANBus, SPI or I2C.
