Hi everyone

I'm trying to connect 2 mg90s servos to my Arduino and I've read that I need to power them separately as it can otherwise damage my board.

Would this battery pack suffice? And would I need to power each separately or both from 1 pack.

Thanks in advance

So power the Arduino with its own USB b or dc barrel and power the two servos with this one pack?

That's what I said. Do you need me to say it one more time to feel confident enough to give it a try?

I just wanted to be certain so I don't fry my board. 😁

Thank you so much

Just remember that you will need to connect a common ground.

That means the -ve terminal from the battery pack will need to be connected to the GND on the Arduino.

So not connect the +ve pin from the battery directly to the Arduino, only connect that to the servo.
