PCA9685 16 CHANNEL 12-BIT PWM SERVO MOTOR DRIVER I2C MODULE ARDUINO PIC

Product description:

_{You want to make a cool robot, maybe a hexapod walker, or maybe just 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 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}

_{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)}

_{• 330 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}
