I am starting the build of a new ArduBoat and am hoping I can get some input on hardware. I have not wired anything but will start the build in the next few days.
I have the new RFD900x with the TXmod JR module, Jumper T16, and Matek F405wing. This will all go into a 24" boat with a custom built seafloor mapping sonar as a research project.
Since the RFD900x TXmod and Jumper T16 are relatively new, I cannot find much information on how they will work together (which is why I thought it would be interesting to try). I have the Yaapu widget successfully installed on the T16 but I am not sure how to setup the T16 for telemetry since I will not be using an RC receiver with telemetry output.
I know that it is suggested to power the RFD900x via a separate BEC when using a PixHawk FC but it looks like the F405’s internal BEC can handle 2 amps which should be sufficient for the 800mA the radio needs. I am already powering the sonar and micro-controller with a separate BEC and would rather not add additional complexity unless needed. Not sure if the recommendation is due to noise or current draw. Any suggestions?
