PX4 airspeed sensor not working on i2c splitter


(Sstage) #1

Pixracer with px4 airspeed sensor (MS4525DO), i2c splitter. On battery power.

For some reason I can only get airspeed to work when nothing else is plugged into the splitter. If I plug in a gps I will get satellites but airspeed will stop reading. Has anyone else had this issue?

MS4525DO is a quite picky for i2c voltage levels, cable length and termination. The best solution is to use an active i2c hub, which takes care of the necessary signal conditioning.

Just bought that. Thanks for the info.
