In this updated video, I address using DCC-EX (EX-Rail) to control LED's using PCA9685 modules. I am still disappointed in this particular video, I want to try to shorten it for one thing, but it does show how to control LED's and signals with DCC-EX. Please note that the examples I give are just that, EXAMPLES. your use will vary and actual programming will likely be different.
Here is the link to the Addresses for the PCA9685
