The Adafruit 16-channel 12-bit PWM/Servo Shield is perfect to build an Arduino robot, an hexapod, drive a lot of LEDs. It works with an Arduino Uno, Mega, ADK.

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. Because I2C is a shared bus you can also connect other I2C devices and sensors to the SCL/SDA pins as long as their addresses don't conflict (this shield has address 0x40)

Features

  • There's an 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.
  • It is 5V compliant, which means you can control it from a 3.3V Arduino and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
  • Adjustable frequency PWM up to about 1.6 KHz
  • 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
  • A spot to place a big capacitor on the V+ line (in case you need it)
  • 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
  • A lot of extra space remaining? Let's turn it into a prototyping area.

Part List

  • 1x shield
  • 4x 3x4 straight header
  • 1x 2-pin terminal block
