Product Overview

You want to make a cool 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 your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs.
  • i2c-controlled PWM driver with built in clock meaning you don't need to continuously send it signals
  • 5V compliant meaning control from a 3.3V microcontroller and safely drive up to 6V outputs
  • 6 address select pins so you can wire up to 62 on a single i2c bus, a total of 992 outputs
  • Adjustable frequency PWM up to about 1.6 KHz
  • 12-bit resolution for each output - for servos, that means about 4µs resolution at 60Hz update rate
  • Configurable push-pull or open-drain output
  • Output enable pin to quickly disable all the outputs
