Lack of explination of wiring between pca9685 and motors / servos #2

Thanks for publishing this, it seems to be the only ROS2 PCA9685 driver around, but I am very confused as to how it is setup. You talk about a steering servo, you talk about 4-Wheel steering, but I am failing to understand what physical / motor / servo setup this is designed for.

I was trying to use it for this hat: https://www.waveshare.com/motor-driver-hat.htm but I am not sure it is suitable.

Thanks Kevin

Looking into this more, this code looks to control 3 servos, Throttle, Steering, and Braking servos - probably as found in a traditional RC Car. So doesnt look suitable for my use. Thanks anyway.
