Adafruit Servo Motor Controller Board 16-Channel 12-bit PWM/Servo Driver PCA9685 I2C Interface


Description:
You want to make a cool robot, maybe a hexapod walker, or a 17-DOF robot or a moving part. 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 (which we would really like to see since it would be glorious)

1. This is an I2C-controlled internal clock driver. The power supply is 5V compatible, which means that you control it from a 3.3V microcontroller and still safely output 6V.
2. 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
3. Adjustable frequency PWM up to about 1.6 KHz
4. 12-bit resolution for each output - for servos, that means about 4μs resolution at 60Hz update rate
5. Configurable push-pull or open-drain output

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 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

This product comes with a fully tested and assembled breakout as well as 4 pieces of 3x4 male straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a piece of 6-pin 0.1" header (to plug into a breadboard). A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do.

Check out the Adafruit tutorial with Arduino and you can get the documented Arduino library which has both PWM and Servo examples!
