Questions & Answers
The answer is yes.
A maximum of 25mA is allowed for each of the 16 outputs. With that in mind, the maximum current available to the board would not exceed
It is these five volts that drive the servo motor. It depends on the load how much current is drawn by the servo. In general, the more servos and loads moved, the more current had to be drawn.

These are the coolest drivers of all time A decent amount of quality has gone into their construction. In addition to LEDs, you can control virtually anything with a PWM input. The servos can also be cascaded, allowing the user to control over 900 motors! Some of the pins arrived bent, however During shipping, they probably got bent out of shape, but reshaping them with needle nose pliers shouldn't be too challenging, and they still work fine. I have 2 6 volt servos connected to a PCA9685, using an Arduino Uno R3 as a platform for controlling them. I use two 10k potentiometers to control the servos. It is pretty neat, yet there is no documentation that comes with them, so if you do not have any knowledge about using these, you may have to do research to fill in the gaps between documents. The Arduino community is fortunately helping to demystify these useful electronic modules by providing essential knowledge on electronics free of charge, while helping to demystify electronics in general. I cannot imagine why a manufacturer would not want an informed public to know what benefits the product they are manufacturing has to offer, but these aren't too hard to handle either. You can do pretty interesting things with these, and there are tons of open source projects that make use of.
I would like to point out that these boards will not take 3mm mounting screws. I suggest you go buy If you do not have any 5mm screws, use 1mm screws. There are metal sleeves around the mounting holes, so drilling them out could damage the board.

On my model railroad, I use the PCA9685 module to power many servos at once. This module is a convenient way to control a lot of servos at the same time. One of the best examples of the product is the HiLetgo module.
Although the headers are clipped into place incorrectly, the product works fine. It is necessary to solder the headers) to connect the normal connectors to the servos. A bent pin was all that needed to be done. The situation is just fine.
There is a low degree of accuracy in pulse measurements. Although this module does work, its PWM accuracy is not very good and will need to be calibrated. It is impossible to get standard 3mm screws to fit into the mounting holes. I wanted a better solution, but I will get by with it.
I bought a couple of these to enable me to add several servos to a project. So far it's working great.
On the raspberry pi it doesn't seem to work very well, and I'm looking at making everything controlled by an Arduino to see if that will help.
I am very happy with it. As specified, worked as expected.
