PWM Channel Support on VOXL 2 and SDK Version Inquiry

cmall

Dear all,

We are currently using the VOXL 2 flight controller and noticed in the documentation (SDK v1.1.1) that only four PWM channels (400 Hz) are supported. Our project requires at least five channels, and ideally, we’d like to utilize all eight channels if possible.

Could you please clarify:

Does the hardware (STM32F103C8T6) support eight PWM outputs, and is this limitation purely firmware/SDK-related?
Is there any change in the latest SDK (or SDK v1.3 if available) regarding PWM channel support?
If expanded PWM support is not yet available, do you recommend any work-arounds (e.g., external PWM expanders) that integrate well with VOXL 2?

We are approaching a hardware-freeze milestone, so any guidance or roadmap information would be very helpful.

Thank you in advance for your assistance!

@cmall the VOXL 2 IO connects via UART. You could use any breakout board, like an Arduino, to generate PWM
