PWM click is a simple solution for controlling 16 PWM outputs through a single I2C interface. You can use it to control anything from a simple LED strip to a complex robot with a multitude of moving parts. The click board carries the PCA9685PW IC. The board has an additional set of pins that allow you to connect up to seven PWM clicks together (using three jumpers to specify a different I2C address for each one). This will allow you to get a total of 112 pwm outputs on a single I2C line. PWM click is designed to use either a 3.3V or 5V power supply.
