16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 Module

16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 Module

Description

16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 Module lets you add more IOs to your microcontroller boards (such as Arduino Boards, Raspberry Pi Boards and more). The Module has chainable I2C interface meaning for even more IOs more boards can be daisy chained. Its  excellent product for Robots that require lots of Servo motors to control using single microcontroller.

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, its completely free running.
  • 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
  • Terminal block for power input (or you can use the 0.1″ breakouts on the side)
  • Reverse polarity protection on the terminal block input
  • Power-good LED
  • 3 pin connectors in groups of 4 so you can plug in 16 servos at once
  • “Chain-able” design
  • A big capacitor on the V+ line
  • 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
