Tinker board S Fan protection againts inductive loads
#1
Hello,

I just received my Tinker Board S and it comes with the fan, which is an inductive load.
Do the board provides protections against reverse inductive currents when the fan powers off ?
I don't see any dedicated connector (other than 5V and GND) to the fan neither any protection diode.

Thank you.

You might look at the schematics
Light blue words might be a link. Have you try to click on them? Big Grin

Hi stickyfinger,

interesting question!

I know about your problem, and if I use inductiv 'parts' like relays i use a flyback diode!

But i never used them for any fan!

You realy frightend me now!!!
(Do I need them for brushles motors, ... and maybe also for speakers to protect the amp?
I never thougt about that seriously before!)

I never used them in this cases!

And you can see here,

I fiddle around with SBC's very often and never had any problem.

(And no, they are not all damaged because of a missing, as we call it in Germany "Freilaufdiode" or "Sperrdiode"!)

Greetigs

Grulle
