16 Channel PWM Expansion Board

Control Servos + PWM devices using this 16 channel PWM Expansion Board. PCA9685

When you run out of PWM Arduino-pins or are on a Raspberry Pi that doesn’t have PWM capability. With this PWM Expansion Board you can control up to 16 PWM driven devices from via 2 I2C pins. Can also be daisy-chained to give you up to 992 PWM outputs.

Features:

  • I2C controlled PWM/Servo driver board
  • Clock on board
  • Operating Voltage: 3.3V – 6V
  • 6 I2C Address Select Pins
  • Max Daisy-chaining: 62 boards for a total of 992 PWM outputs
  • Max PWM frequency: 1.6 kHz
  • Resolution: 12 bit
  • Configurable Output (push-pull or open-drain)
  • Output Enable (OE) allows you to turn off all outputs at once
  • Onboard Features:
    • Polarity Protection
    • Power Indicator LED
    • Optional capacitor solder point for smoothing
      • Address Select Jumpers
