16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

<p>If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with <strong>PWM</strong> outputs,   then the limited <strong>PWM</strong> outputs of your microcontroller would be a big problem for you. To overcome this problem, the only thing you should do is to get a<strong> 16-Channel 12-Bit PWM/Servo Driver</strong>.</p> <p>You can control <strong>16 free-running PWM outputs</strong> with<strong> 16-Channel 12-Bit PWM/Servo Driver</strong> using only <strong>2 pins</strong>. You can even chain up 62 breakouts to control up to <strong>992</strong> <strong>PWM</strong> <strong>outputs</strong>.</p> <p>It’s an <strong>I2C</strong>-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!</p> <p>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 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.</p> <hr /> <h4><strong>Features :</strong></h4> <ol> <li>Adjustable frequency PWM up to about 1.6 KHz</li> <li>12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate</li> <li>Configurable push-pull or an open-drain output</li> <li>The output enable pin to quickly disable all the outputs</li> <li>Terminal block for power input</li> <li>Reverse polarity protection on the terminal block input</li> <li>Green power-good LED</li> <li>3 pin connectors in groups of 4 so you can plug in 16 servos at once</li> <li>Chainable design</li> <li>A spot to place a big capacitor on the V+ line</li> <li>220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.</li> <li>This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.</li> </ol> <hr /> <h4><strong>Package Includes :</strong></h4> <div>1 x 16-Channel 12-bit PWM/Servo Driver</div>
