DSHOT on PX4 with CubeOrangePlus and Mini Carrier Board

Cube Autopilot
1

Hello,
I would like to configure my DSHOT ESCs to run on the MiniCarrierBoard of my CubeOrangePlus using PX4.
I am using the copter configuration and for PWM it works, but not for DSHOT.
ESC and wiring is perfectly fine because the same setup runs on ardupilot.
I assume that PX4 just doesn’t support it on the minicarrierboard because DHSOT should be configured on the AUX ports which the minicarrierborard does not have. (I follow this manual: https://docs.px4.io/main/en/peripherals/dshot.html)
Is that correct? What can I do about it?

Thank you for your help.
Sam

When using PX4, DSHOT only works on the AUX outputs for a Cube.
So you would have to move the connections, and change any other related parameters, such as in the actuator configuration screen

So in the case of the Mini Carrier Board, that only has MAIN Outputs, DSHOT is not possible?

There are AUX outputs on the header pins near Power2

If I am hooking up my esc to the AUX pins as you showed here, I am assuming that I would just wire motor 1 to AUX 1 and so on?

Yes correct, and you also need to connect a ground wire for the ESC signals to some ground pin on the flight controller.
There’ll be a bunch of PX4 parameters you have to change too - check in the PX4 docs or over at px4.io
