Hello! I am designing the circuits to condition the inputs and outputs of the ESP8266 and the RaspberryPi for the industrial environment, I did not have problems with the digital outputs and inputs, nor with the analog input of the ESP, but I was hindered by the analog output based on PWM, not I like the idea of ​​a low pass filter, will not you know of some other option to transform the PWM signal into analog voltage?
