Key Features

PCA9685 contain an I2C communication PWM driver with a built in clock, so you do not need to continuously send it signal tying up your microcontroller
Green power indicator lamp, 3 pin connectors in groups of 4, so you can plug in 16 servos at one time(servo motor plug slightly wider than 0.1 inch)
Using only two pins, control 16 free-running PWM, so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs
12 bit resolution for each output for servos, that means about 4us resolution at 60Hz update rate
PCA9685 IIC module 5V compliant, you can also control it from a 3.3V microcontroller and still safely drive up to 6V outputs
