16 Channel 12-bit PWM/Servo Driver-I2C interface PCA9685 module for arduino or Raspberry pi.

You want to make a cool robot, maybe a hexapod walker, or maybe ju a piece of art with a lot of moving parts.

Or maybe you want to drive a lot of LEDs with precise PWM output.

Then you realize that your microcontroller has a limited number of PWM outputs! What now?

  Using only two pins, control 16 free-running PWM outputs!
You can even chain up 62 breakouts to control up to 992 PWM outputs
It's an i2c-controlled PWM driver with a built in clock. That means that,
unlike the TLC5940 family, you do not need to connuously send it signal tying up your microcontroller,
  its completely free running!
It is 5V compliant, which means you can control it from a 3.3V microcontroller and ill safely drive up to 6V outputs
  (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot
of servos or LEDs
Adjuable frequency PWM up to about 1.6 KHz
12-bit resoluon for each output - for servos, that means about 4us resoluon at 60Hz update rate
Configurable push-pull or open-drain output
Output enable pin to quickly disable all the outputs
We wrapped up this lovely chip into a breakout board with a couple nice extras
Terminal block for power input (or you can use the 0.1" breakouts on the side)
Reverse polarity protecon on the terminal block input
Green power-good LED
3 pin contors in groups of 4 so you can plug in 16 servos at once
(Servo plugs are slightly wider than 0.1" so you can only ack 4 next to each other on 0.1" header
"Chain-able" design
A spot to place a big capacitor on the V+ line (in case you need it)
330 ohm series resiors on all the output lines to protect them, and to make driving LEDs trivial
Solder jumpers for the 6 address select pins
