16 Channel PCA9685 12-bit PWM Servo Shield Motor Driver I2C

  • 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

Product details

Features

  • 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 signal tying up your microcontroller, it’s completely free running!
  • It is 5V compliant, which means you can control it from a 3.3V microcontroller, with 3.3V logic pull-ups, and still safely sink up to 5.5V outputs (this is good for when you want to control common-anode white or blue LEDs with 3.4+ forward voltages)
