Hey!

I have been through the Documentation of FlightCoreV2. Apart from availability of PWM Main Pins, is there availablility of PWM AUX Pins as well? If yes, how do I enable and use them?

I'm planning to intergrate Gimbal Camera with Flight CoreV2 on PX4, hence would be needing PWM AUX Pins for the same.

Hi @Jetson-Nano 
Can you elaborate what you mean by "main" vs "aux"?
We provide 8 channels of PWM as you may know. Are you asking if we provide more than 8 natively?

@Vinny Thanks for reverting. Yes, as you mentioned there are 8 channels of PWM. Apart from using 4 channels for controlling 4 Motors on quadcopter, I would like to use rest of the available ones to control neopixel, an external led strip using one of the AUX outputs. 

But as per the documentation, I'm not able to see how to access the AUX outputs. Could you please help?

@Jetson-Nano It should be no different than with any other flight controller hardware running PX4. The PX4 documentation should be able to explain how to do that.
