Fancy making a cool robot such as a hexapod walker for your Raspberry Pi or Arduino, or maybe you want to drive a lot of LEDs with precise PWM (Pulse Width Modulation) Output? The Raspberry Pi only has one hardware and one software PWM output, so you'll need this 16 Channel 12 Bit PWM and Servo Driver Breakout Board, so drive on multiple channels!
You can control up to 16 free-running PWM outputs using only two pins and you can even chain up 62 breakouts to control up to 992 PWM outputs. It's an i2c-controlled PWM driver with a built in clock which means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
The PWM/Servo Driver uses I2C so it take only 4 wires to connect to your Arduino:
