I know the subject of external IMUs for ardusub has been asked before here, but this seemed to be pixhawk specific.
My understanding is that there has been progress in ardupilot master to support external IMUs as of this github issue. But that sounds a bit too down the pipeline for what I’m looking for.
I did some preliminary research for different flight controllers and I didn’t find too many that ArduSub said it supported. So, the question: Does anyone know of a flight controller that works with ArduSub that I could plug in and external IMU to?
