Good day,
Can someone advice whether the power supply rails for the PWM_AUX OUTPUT is independent from the PWM_MAIN OUTPUT ports on a Orange CUBE OR are they all joined together as +ive & -ive .
thank you
They are all counted as servo rail, so their +ve and gnd are joined together.

Hi Again,
Can you please advice what all parameters on CUBE Orange do we set ( Px4 stack) and check in order to get going with using PWM _AUX 1 channel with a third party interface board .
thank you
These should be the parameters

Hi,
I am trying to set the AUX_Main_channel 1 ( used Channel 9 on my Herelink) thro’ Px4 - Orange CUBE . Please can you advice what is the equivalent function for Brd_PWM_Count in Px4 . I am not seeing any changes !
Attached images of my AUX settings below if this information helps .
I think it’s probably PWM_AUX_OUT but I’m not familiar with px4, so I’m not sure. You may ask this on the px4’s forum.

But this is related to QGC and Herelink even though Px4 is the stack. I am surprised no one has configured Aux channels in their drone setup 
Some links to the same question in CUBE / Px4 forums
QGC is an interface to modify the parameters in autopilot firmware. It has nothing to do with your question, Herelink as well.
As long as ardupilot is capable of doing this, we can know that there is no problem in hardware.

Good day,
Please can you advice the setup link for Ardupilot using the Aux channels. I am not seeing thro’ the Px4 forum any successful AUX setup procedure.
Perhaps i need to switch to Ardupilot instead of Px4 
You may get the information from Arudpilot wiki
