Hi there. I was wondering how to access the raspberry pi’s PWM through the automation hat? I was hoping to use it along with a low pass filter to output from 2-10V DC to control another device.

If PWM won’t work, how else would I be able to control a 2-10V signal from the automation hat? Would I need to bring in an external power supply? Could I use the ADC somehow?

Thanks
