SunFounder PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino and Raspberry Pi

With the 2 PCBs that I purchased, I can now drive 64 Servos total.Yes, 64 Servos. Your PCBs control 32 of these servos...ZERO issues. Excellent product.I would say I'd buy again... but I don't even have 64 servos yet !!!!!If I ever buy more than 64 servos, I'll buy these again to drive them, no question.These PCBs work fantastic. Thanks.

I like this servo driver, so far so good - no issues. I like that it is already soldered and comes with capacitor which will prevent voltage drops when using multiple servos (however I've not tested more than 2 servos yet so I can't confirm). Price is good and quality high. I will write an update in couple of months as I'm using it to open / close some tiny doors few times daily, we will see how it performs after some time.

I bought two of these things to go with my Arduino MEGA and also an UNO. The Arduino(s) drive this board, and then I used the PWM outputs to drive logic level MOSFETS which in turn control 12V 1-amp LEDs. You can get the PCA9685 library from AdaFruit that Arduino uses to control the board.Everything works great! I've got LEDs all over the place and am worried that I might be starting to hallucinate from all of the flashing and strobing. :(

Great value!

I liked this servo controller because their software was easy to download and install. It programmed well, but unfortunately caught fire when used with a robot arm. However, I am not sure if it was receiving less power than it needed. It would have been nice if the manufacturer had put instruction guide which listed power requirements. This controller could handle up to 16 servos, but you need to know how much power to give it per servo. I liked the controller, just wish it had not caught fire. Fortunately, it only damaged the controller, but smelled up the house.

Work well, no issues. Use the adafruit library. You can put these in series and have a ton all controlled through I2C. I'm using a raspberry pi and removed the headers on the ends and replaced with JST plugs to make it more compact. Those Dupont connectors are big.

This is working perfectly with my raspberry pi to control the servos on a RC car. Very easy to use, no issues.

My only problem at this point is that the size of the board doesn't line up with the standard pi bonnet size. And sadly the details of the dimensions are no where to be found. The SunFounder wiki says the board is 62x26mm. Which is probably about right, but it would be nice to be able to find a layout of the board, including the exact location of the mounting holes. That information could be used to build a case with the stand offs in the right location. Other manufacturers have descriptions of the board layouts and not having that here makes installing it in a special built case, time consuming and difficult.
