Product Description

Details

Features
 Contain an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running!
 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good when you want to control white or blue LEDs with 3.4+ forward voltages)
 Support using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs
 3 pin connectors in groups of 4, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate

Technical Details
Introduction
PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.

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. :(
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.

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
I like this servo driver, so far so good - no issues.
