The Grove - 16-Channel PWM Driver is based on NXP PCA9685, is a 16-Channel, 12 bit I2C PWM driver. This board can drive up to 16 servos with an external power supply. You can control this board with Arduino easily via the I2C Grove interface. In addition, you can use this board as a LED controller.

Typical applications of this driver include:

• 1 MHz Fast-mode Plus compatible I2C-bus
• 6 Hardware address pins allow 62 PCA9685 devices to be connected to the same I2C-bus
• Low standby current
• Noise filter on SDA/SCL inputs
