JZK PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot

• Using an I2C-controlled PWM driver with a built-in clock. Unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; It run completely freely!
• 5V compliant. You can control it from a 3.3V microcontroller and safely drive up to 6V outputs (good for controlling white or blue LEDs with 3.4+ forward voltages)
• With just two pins, you can control 16 free-running PWM outputs - even chain up 62 breakouts to control up to 992 PWM outputs
• With 4 groups of 3 pin connectors, you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1")
• 12-bit resolution for each output. About 4us resolution at 60Hz update rate for servos
