I dont use an Iron cored transformer and the usual bridge rectifier and electrolytic that was typically used before.
This Nano controller uses the ZMPT107-1 2mA/2mA miniature transformer which is used for AC voltage sense, the secondary feeds a precision full wave rectifier and there is minimal filtering along the feedback path combined with a low pass filter at the voltage feedback input of the Nano.
As far as I know the loop updates are the same but I will leave the definite answer for Poida to confirm.
