Description Standard servo connection jack, signal, VCC, GND. Signal connection pin from 0 ~15, support up to 15 servos. Only use arduino I2C interface, and external power 5V supply. Selectable I2C address by jumper, selectable VDD power supply for PCA9685. Servo power indicator, board logic power indicator. Package include main board, and break away pin header, if you need special arduino stackable pin header please consider to buy it alone, also in store. Using only two I2C pins, control 16 free-running PWM outputs! 6 address select pins, You can even stack up 62 shields to control up to 992 PWM outputs, you can control a lot of servos or LEDs. Because I2C is a shared bus you can also connect other I2C devices and sensors to the SCL/SDA pins as long as their addresses don’t conflict (this shield has address 0x40) Independent power steering, largest input V 6V Logic signals and logic output 3-5v power independent Frequency 40-1000Hz, adjustable frequency PWM up to about 1.6 KHz Number of channels: 16 channels Resolution: 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate arduino libraries include examples avaialble. There’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! Configurable push-pull or open-drain output Three pins signal-VCC-GND design. Stackable design for arduino 220ohm resistors for all the output, protective design for driving LEDs.
