In this video lesson we learn how to control servos on the Jetson Xavier NX using a PCA9685 Servo control board. We show how to connect and wire up the system, how to download and install the libraries, and then how to program the servos to do what we want. Our objective is to control a pan/tilt camera mount for the Raspberry Pi camera. Remember it is best practice to not power the servos from your single board computer. You should use a battery or power supply for the v+/ground header on the PCA9685 board. The Jetson just powers the board through Vcc. if you want to play along at home you can get the gear HERE:
Here is the bracket/servo system, I suggest two sets.

You will also need a simple power supply to provide power to the servos. A nice benchtop power supply will work, or this is a low cost option:

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.

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:
