16-Channel 12-Bit PWM/Servo Shield - I2C Interface
By Adafruit Industries (1411)
So you want to make a cool Arduino robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that the Arduino has only a few PWM outputs, and maybe those outputs are conflicting with another shield! The PWM and Servo driver shield is Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, its all good.
