IIC PWM Servo Driver Arduino Shield, PCA9685

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.
