6.What problems are you experiencing?
I have recently bought an Arducam IMX477 12MP PTZ Camera, which includes the two servos which I’m trying to get working for the first time. I can see where all the cables go on the Raspberry Pi apart from the two labelled ‘Servo VCC’/‘GND’ on the diagram at:


From looking at the video of the camera at:


It looks like it’s being powered from a USB cable, but the video isn’t 100% clear.

Please can you tell me:

What voltage the servos need and what is their maximum current draw?
If I can simply connect these Servo VCC cables to pins on a Raspberry Pi 3B+/4B board?
If I can draw the power from a USB port on a Raspberry Pi?
If so is there are is an off the shelf connector to convert from a USB A male connector to pins suitable for the Servo VCC connectors?

7.What attempts at troubleshooting have you already made?
Read the documentation, searched the forums and Googled.
8.How would you like us to help you?
