I have purchased a PCA9685 16-Channel Servo Driver and have not been able to get it to work, when I run the Servo example the servo motors do nothing. Tested with 2 versions of Arduino Uno, using 2 different computers with different operating systems (MacOS & Ubuntu).
In the video of the following link I show the connections of the pins, the power supply (PC power supply), the voltage measurement, everything. I have checked everything numerous times and wonder if I am doing something wrong or if the module is faulty.

Note: the video is not "searchable" on YouTube, it is possible to access it only if the link is known, I have posted it only so that the pin connections can be seen, etc., and I will remove it when I have confirmed if I am doing something wrong or if the module is faulty.

That does not appear to be an Adafruit board. The seller or manufacturer should be able to help you with technical issues.

Thank you. So the problem is the board, not the connections made by me?

I don't see any obvious issues with the wiring.
