I am a complete noob when it comes to raspberry. I have 2 servos MG996R that I need to power from an external power supply. Currently I am doing it from the board, and when I turn both of them the board just shuts down.

I would really appreciate if you can suggest me a power suply that plugs in to a wall (as opposed to battery-one) and please feel free to explain how to do it as if I am 5-years old. I really have no idea how to connect anything.

Also feel free to post amazon/ebay links to power supplies. The servos I am using are these: https://www.amazon.co.uk/Diymore-Digital-Helicopter-Airplane-controls/dp/B07DQFXDC9/ref=sr_1_5?dchild=1&keywords=servos&qid=1614800439&sr=8-5

The raspberry model is 4-B.

I would suggest using a Raspberry Pi servo hat if you're just starting out and want to learn how to use servos.

There are a lot of them on the market but I'd go with something from Adafruit as they have a lot of very nice tutorials to go along with their products.


On that page they also link to an article on external power supply's to be used with the hat.



To connect a servo via a breadboard and an external power supply you can have a look at this video: https://www.youtube.com/watch?v=LwEBB6v559I

Adafruit also has a tutorial on this: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-8-using-a-servo-motor

Both uses batteries (I know you don't want to use batteries) but it will show you how to connect things. You can always swop out the battery pack for a power supply.

As for a power supply that you can use, Adafruit recommends this for up to 4 servos: https://www.adafruit.com/product/276

The specification that you're looking for is 5V 2A.

Perhaps these Amazon links will help:



  • Hi there, thanks for the reply! I already have the servos, I have left an amazon link to them in my original post. I've checked the link you have provided but I think this is more complicated than what I want to achieve and I am getting a bit lost. I only need to make sure they are properly powered on and need help with what power supply to buy and how to connect the wires. I understand these hats might be helpful, but I don't have one available to me right now and I am sure there must be another way.
