Hello!
I have 5 MG996R servos connected to "Gravity IO Expansion Shield for Arduino V7.1" I have attached an image of the project.
.
I have no idea how much volts/amps to connect to safely turn the 5 servos with load without them all blowing out.
3 questions:
- How much power to connect?
- Also, can I use a battery pack with many 1.5v batteries? Do I go purchase a psu?
- Lastly, I connect the power to SERVO_PWR on the shield, right?
I really want to do this right -- any help hugely appreciated. Thank you so much for spending your time replying to this message -- it really means a lot

Lets figure this out. Google should have shown you that the servos take 2.5 amps at 6 volts to start to move. So, you decide how many servos will try to move at one time. Multiply that number by 2.5 and you will know the current needed at 6 volts.
As far as question #2, what batteries? You can put many 1.5 volt batteries in series to get 6 volts, and then put many of those sets in parallel to get the current needed to operate the servos. So, a PSU rated at 6 volts and the number of amps you need is probably a more economical solution.
The answer to question 3 is yes. The connectors have several pins connected together to handle the power necessary for the servos.
Hope this helps.

Hi,
- How much power to connect?
based on the specification it will need 3.3V/5V operating voltage
