PCA9685 contain an I2C-controlled PWM driver with a built-in clock. 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. Support using only two pins to control 16 free-running PWM outputs . 3 pin connectors in groups of 4, so you can plug in 16 servos at one time . 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
