  • It's an i2c-controlled PWM driver with a built in clock
  • 5V compliant, can control it from a 3.3V microcontroller and still safely drive up to 6V outputs
  • 6 address select pins so you can wire up to 62 of these on a single i2c bus
  • Adjustable frequency PWM up to about 1000Hz
  • 12-bit resolution for each output - for servos
  • Configurable push-pull or open-drain output
  • Output enable pin to quickly disable all the outputs
  • 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 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)
  • 220ohm series resistors on all the output lines 
  • Solder jumpers for the 6 address select pins
  • Application: To make a cool robot, a hexapod walker, or a piece of art with a lot of moving parts or to drive a lot of LEDs with precise PWM output
