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! Parameter: Power input terminal Green power indicator In the 4 groups of 3-pin connector to facilitate the insertion of 16 servo motor (servo motor plug slightly wider than 0.1 ") The polarity of the reverse polarity is input on the terminal block Voltage: DC5-10V power supply Communication Interface: IIC 16-way steering gear control 1.Output enable pin to quickly disable all the outputs 2. Terminal block for power input (or you can use the 0.1" breakouts on the side) 3. Reverse polarity protection on the terminal block input 4. Green power-good LED 5. 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. V + line to place a large capacitor, the maximum external input voltage depends on the 10V 1000uf capacitor All PWM output lines have a 220 ohm series resistor protection and can easily drive LED 330 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial. Solder jumpers for the 6 address select pins. Package including: 5pcs x PWM Servo Motor Driver

16 Channel PWM/Servo Driver IIC interface-PCA9685 for arduino or for Raspberry pi shield module servo shield. 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate. 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs. Communication Interface: IIC, PCA9685 contain an I2C-controlled PWM driver with a built-in clock. 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).
