16-Channel 12-Bit PWM/Servo Shield - I2C Interface: stack up to 62 shields

This shield, which comes assembled and tested, will appeal to robotics engineers who like to push back their limits. If your project includes a host of servos, or if you want to control a multitude of PWM LEDs without monopolising the outputs on your Arduino, the 16-Channel 12-Bit PWM Shield is the stuff of dreams.

The I2C link is established thanks to its 2 pins (SDA and SCL). Above all, it has 6 addresses selectable by soldering allowing you to stack up to 62 Arduino shields – making a total of 992 PWM outputs!

A host of project possibilities

The 16-Channel 12-Bit PWM/Servo Shield with I2C interface also has a blank prototyping area, 2 voltage LEDs (Vdc and V+), reverse polarity protection on the terminal block input, a group of 3-pin connectors per channel for direct servo connections, a capacitor connection slot, etc.

Technical specifications of the 16-channel 12-bit PWM shield

  • Its built-in clock means you don’t have to continuously provide a PWM value, the circuit makes the necessary output adjustments itself
  • 5V compatible, so you can control it from a 3.3V Arduino
  • Adjustable frequency PWM up to 1.6 kHz
  • Configurable push-pull or open-drain output

Included with the shield:

  • 4 X 4x3 headers for connecting servo motors or LEDs
  • 1 X 2-point screw terminal block for external power supply
  • 1 X 36-pin header for the shield part

  • Dimensions (without headers and terminal block): 54 x 70 x 3 mm
  • Uses I2C 7-bit addresses between 0x60 and 0x80, selectable with jumpers
