PCA9685 16 Channel PWM Servo Driver I2C Module for Robotics

 

Features

  • The pca9685 Using only two pins, control 16 free-running PWM, so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs
  • The PCA9685 chip is wrapped in the center of the board
  • Contains an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running!
  • 12-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz.
  • 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage
