@Alex-Kushleyev Thank you for the quick response Alex.

I don't necessarily need to develop my own code and flash the board, it's just the method I am familiar with working with previous uC...
But if I were to implement my sensors/pwm outputs through PX4 what would be the recommended steps to do so? Is there git libraries already available for it? If so, can I still change code snippets to operate under my conditions? or parameters in Qgroundcontrol?
Sorry if I am not clear with my questions but I'm pretty new to these types of complex architectures...

Thank you again Alex and the Modal AI team

@Alex-Kushleyev Hi. Sorry for the delay in my response.
Currently i would just like to know how do i flash the board with my code to control a simple servo motor, or the luminosity of an led... What's the best approach to do that? I can't find any information on the SDK regarding the I/O expansion board.

Later on, I would like to connect solenoid valves (On/Off) (i don't require a pwm output but that is the only I/O I have access).

Hi Modal AI Team.

I was wondering how I can connect inputs like sensors to voxl2 to read and process data. My current attempt is through m0065, the voxl2 io expander board but i dont quite get how i can flash the board to control and read the pwm channels (which i believe to be the only gpio available)..
Please let me know if this is even feasible at all.

Thanks in advance!!
