Hi forum members,

 

To consider an appropriate power supply for my Netduino Plus 2, what is suggested?

• Power using the Micro USB connector (5V), or
• Power using the discrete power socket for 7.5-9V

If I use an external power supply with 5V and connect it through the Micro USB port, will it provide sufficient power to the netduino including all pins (PWM, ...)?

 

(I can't find any available industrial power supplies with 7.5 - 9V, so I'm thinking of using 5V instead).

(I guess I can't use 5V input on the power socket?)

 

Thanks for your advice!

Yes.

You don't need an industrial grade power supply, a wall adapter is sufficient.

No, the onboard linear regulator requires at least ~6.5 V input.

Thank you, CW2

 

I don't want to use a standard wall adapter, as my Netduino will go to a production environment. I can't rely on cheap China crap...

Putting a Netduino into production and calling wall warts cheap china crap is pretty much an as far from a success story as you can get. Good luck. Where do you think all the parts on your Netduino are made?

Main problem with wall chargers is heat. Tiny cases also keep the heat inside. So i prefer a dedicated power supply that will last.

I understand that most electronic parts originate from China (including the Netduino). It's not allover a quality issue, but in my experience wall chargers will not last too long for 24/7. That's what I call "China crap".
