This library is used for Arducam Pan Tilt Camera for Raspberry Pi, as well as for the Upgraded Camera Pan Tilt Platform for Raspberry Pi, Nvidia Jetson Nano/Xavier NX.

On Raspberry Pi, make sure that ic2 support is enabled within the raspi-config tool, as explained here in more details. It is required, so Python can find the board which drives the servos.
