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.

Product Description

Features

  • Using only two I2C pins, control 16 free-running PWM outputs! You can even stack up 62 shields to control up to 992 PWM outputs
  • I2C-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
  • 5V compliant, which means you can control it from a 3.3V Arduino and still safely drive up to 6V outputs
  • 6 address select pins so you can stack up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
  • stable frequency PWM up to about 1.6 KHz
  • it resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
  • Configurable push-pull or open-drain output
  • Terminal block for power input (or you can use the 0.1" breakouts on the side)
  • Reverse polarity protection on the terminal block input
  • Green and red power-good LEDs
  • 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
