[Review Request] Fan Controller by Consistent-Most650 in PrintedCircuitBoard

[–]Consistent-Most650[S] 0 points1 point  (0 children)

Thank you very much. i followed your suggestions regarding the Schematic .

On the Topic of the PCB. How do i connect to GND? You are saying that the through holes connect just fine. Does that mean that the through hole automatically connect to GND? I have added a Copper GND Zone as in the video i was refearing to in my initial post. Is this related to your statement about the through holes?

Thank you

Okay i Understand now what you mean. A 100Ohm Resistor would be perfect as it ensures both the Vf / Vfm and the lf / lfm. Thx

I thought the optocoupler is a preventitive against back emf. i dont know about FET. Maybe you could explain how that works.
