In this video lesson we learn how to point two raspberry pi cameras on the Jetson Xavier NX using a PCA9685 Servo control board, and two pan/tilt camera mounts. We show how to independently point each camera, while live video is being taken. Our objective is to control a pan/tilt camera mount for the Raspberry Pi camera. if you want to play along at home you can get the gear HERE:

Here is the bracket/servo system, I suggest two sets.

It is never a good idea to power servos from an expensive single board computer. Dont use your board as a power supply. The power supply below allows you to power the servos through the screw connectors on the PCA9865.

Also I am suggesting two raspberry pi camera, version 2. I like the units below because they include the long cable.

This camera also has a cool little acrylic case, which is nice.

This is the other NVIDIA Jetson Xavier gear I am using.

If you are not ready for the Jetson Xavier NX, you can follow these lessons using a Jetson Nano, Available below:

I love this cool Acrylic case with fan:

I like to run with minimum wires, so I am running this wifi card, which works very well. If your budget is tight just use an Ethernet cable, as all my lessons will work with just an ethernet cable.

Finally, you can use either a Logitech C920 WEB cam or the Pi Cam. I am using both, but you need at least one camera working with the nano:
