Description

Do 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.

  • It’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 signals tying up your microcontroller, it’s completely free running!
  • It is 5V compliant, which means you can control it from a 3.3V microcontroller 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)
  • 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs – that’s a lot of servos or LEDs
  • Adjustable frequency PWM up to about 1.6 KHz
  • 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate
  • Configurable push-pull or open-drain output
  • Output enable pin to quickly disable all the outputs
  • Terminal block for power input.
  • Reverse polarity protection on the terminal block input
  • Green power-good LED
  • 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
  • “Chain-able” design
  • 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
  • Solder jumpers for the 6 address select pins

This product comes with a 2-pin terminal block (for power). A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15-minute task that even a beginner can do.
