When using GPS class with an Arduino (or similar microcontroller), be sure to upload the StandardFirmataPlus firmware to your board.

Adafruit Ultimate GPS Breakout

Example of Adafruit Ultimate GPS on serial.


Fritzing diagram: gps-adafruit.fzz


Run this example from the command line with:

node eg/gps-adafruit.js
const { Board, GPS } = require("johnny-five");
const board = new Board();

board.on("ready", () => {

   * This is the simplest initialization
   * We assume SW_SERIAL0 for the port
  const gps = new GPS({
    breakout: "ADAFRUIT_ULTIMATE_GPS",
    pins: {
      rx: 11,
      tx: 10,

  // If latitude, longitude, course or speed change log it
  gps.on("change", position => {
    const {latitude, longitude} = position;
    console.log("GPS Position:");
    console.log("  latitude   : ", latitude);
    console.log("  longitude  : ", longitude);
