  • Configurable push-pull or an open-drain output
  • The 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
]]> Description of Servo Driver PCA9685 PWM I2C 16 Channel 12 bit

Summary PCA9685 based servo controller

This board features PCA9685. With this you can control 16 servos simulteneously.

Features:

  • It’s an i2c-controlled PWM driver with a built in clock.
  • 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

The board comes with-

  • Terminal block for power input (or you can use the 0.1″ breakouts on the side)
  • Green power 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
  • 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.
