"WebThe ESP8266 actually lacks hardware PWM! It's all done in software. Thus, it will never be perfect, especially at very low duty cycles. If you want buttery smooth PWM at all duty cycles, as well as higher frequencies, go with ESP32. The difference is night and day. ESP8266 can do it, sort of, but it is a serious compromise.
