PCA9685 16-Channel 12 bit PWM Servo Driver I2C Interface-10pcs

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 to signal to tie up your microcontroller, it's 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 LEDsAdjustable frequency PWM up to about 1.6 kHzConfigurable push-pull or open-drain outputOutput enable pin to quickly disable all the outputsWe wrapped up this lovely chip into a breakout board with a couple of nice extrasTerminal block for power input (or you can use the 0.1" breakouts on the side)Reverse polarity protection on the terminal block inputGreen power-good LED3 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" designA 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 trivialSolder jumpers for the 6 address select pinsPackage Included:1 x PWM Servo Driver
