Features: 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 signal tying up your microcontroller, its completely free running! Output enable pin to quickly disable all the outputs. -The PCA9685 chip is wrapped in the center of the board -16-way steering gear control -Power input terminal -Green power indicator -Using I2C communication, built in PWM driver and a clock. -Compatible with 5V,can also use 3.3V MCU control and safely drive to 6V output. -Address selects pins, so you can put 62 driver board hanging on a single I2C bus, a total of 992 PWM outputs. -About 1.6Khz adjustable frequency PWM output. -Ready to output 12 resolution of the stepper motor, which means that at 60Hz refresh rate can reach 4us resolution. Technical Parameters: 1.Voltage: DC5-10V power supply 2.Communication Interface: IIC 3.16-way steering gear control 4.Size: 62mm x 25mm x 13mm Package includes: 3 X PCA9685 PWM Servo Motor Driver Board Controller Module

12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate. 3 pin connectors in groups of 4, so you can plug in 16 servos at one time . Supports using only two pins to control 16 free-running PWM outputs ¨C you can even chain up 62 breakouts to control up to 992 PWM outputs. 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). PCA9685 Contains an I2C-controlled PWM driver with a built-in clock; Power supply voltage is DC5-10V.
