node.js /i2c control for the Adafruit PWM servo driver

Adafruit I2C PWM Driver

Node.js implementation for the Adafruit 16-Channel 12-bit PWM/Servo Driver

PwmDriver = require('adafruit-i2c-pwm')
pwm = new PwmDriver  0x40 '/dev/i2c-1'

To configure I2c on your Raspberry-pi / Beaglebone please see :


  • [PwmDriver(address:Number,device:String,debug:Bool)]

Setting up a new PwmDriver

  • address: Address of the i2c panel, e.g. 0x20
  • device: Device name, e.g. '/dev/i2c-1' (defaults to /dev/i2c-1)
  • debug: flag used to display debug messages


Based on the Adafruit's Raspberry-Pi Python Code Library

Here is a growing collection of libraries and example python scripts for controlling a variety of Adafruit electronics with a Raspberry Pi

In progress!
