16 Channel 12-bit PWM/Servo Driver-I2C interface PCA9685 module Raspberry pi shield module servo shield

Description:
Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.
Features:
Dimensions (no headers or terminal block) 2.5" x 1" x 0.1" (62.5mm x 25.4mm x 3mm)
Weight (no headers or terminal block): 5.5grams
Weight (with 3x4 headers & terminal block): 9grams
This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
Terminal block for power input (or you can use the 0.1" breakouts on the side)
Reverse polarity protection on the terminal block input
Green power-good LED
3 pin connectors 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 stack 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)
220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
Solder jumpers for the 6 address select pins
i2c-controlled PWM driver with a built in clock. Unlike the TLC5940 family, you do not need to continuously 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 still 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
Adjustable frequency PWM up to about 1.6 KHz
12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
Configurable push-pull or open-drain output
Output enable pin to quickly disable all the outputs
