PCA9685 -- More Picts - Open image

This is an i2c-controlled PWM drive and a built-in clock. This means that it will and TLC5940 series are very different. You do not need to constantly send signals occupy your microcontroller
It is 5V compatible, which means you can also use 3.3V MCU control and safely drive to 6V output (when you want to control white or blue LEDs with 3.4+ positive voltage is also possible)
Address select pins so you can put 62 driver board hanging on a single i2c bus, a total of 992 PWM outputs. That would be a very large resource.

Output Enable pin to quickly disable all output
Central PCA9685 chips are wrapped in small plates
Power input terminals
Green power indicator
Facilitate you in four groups in a 3-pin connector insert 16 servo motors (servo plug slightly wider than 0.1in, so you can put four pairs of 0.1in connector)
Reverse polarity protected wiring board input
Cascade Design
V + line to place a large capacitor (in some cases you will need)
All PWM output lines have put a 220 ohm series resistor to protect them, and can easily drive the LED.

This device is on i2c address: xx
