Description: It's an i2c-controlled PWM driver with a built in clock. 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. 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. The PCA9685 chip is wrapped in the center of the panel. 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 can easily drive LED. Package Includes: 1 Piece 16 Channel 12-Bit PWM Servo Motor Driver
