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! What now? You could give up OR you could just get our handy PWM and Servo driver shield. It's just like our popular PWM/Servo Breakout but now Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, its all good.

Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface (5:58)

Technical Details

Dimensions (no headers or terminal block) 2.1" x 2.7" x 0.1" (54mm x 70mm x 3mm)
This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.

Revision History:

Dec 3, 2014 - we updated the polarity protection transistor to an AOD417 for better current handling, it is otherwise identical in code and size.
