GPS

Easily view realtime NMEA data on Google Maps

Overview

GPS is a Node.js application based on GPS.js that allows you to view NMEA data coming from a GPS module on Google Maps.

It is designed to be used with an Arduino microcontroller, but can be used with any device that can send NMEA data over a serial port.

Features

• Realtime data visualization
• Keeps track of every GPS fix (until you reload the page)
• Runs on every platform that supports Node.js
• Open source
• Free
• It's easy to use

Requirements

Software

• Node.js (v19.5.x)
• Git (optional)
• Arduino IDE
• Supported web browser (Chrome, Firefox, Edge, Safari, etc.)

Hardware

• Arduino
• GPS module (NEO-6M)
• Radio module (APC220) (optional)
• USB to UART Bridge (CP210x) (optional)
• Breadboard
• Jumper wires
• USB cable
• Computer

APC220 Setup

Disconnect the APC220 from the Arduino before proceeding.

1. Upload the apc220Cfg.ino sketch to your Arduino

2. Disconnect the Arduino from your computer

3. Connect the APC220 to the Arduino on the GND, 13, 12, 11, 10, 9 and 8 pins

4. Connect the Arduino to your computer

5. Open the Serial Monitor

6. Type m and press Enter

   • It should bring up a menu like this:

   

7. Follow the 'Write example' instruction and if you want, change the frequency

   • Save the frequency you chose (you will need it to configure the other APC220 module)

8. Disconnect the Arduino from your computer

9. Disconnect the APC220 from the Arduino and connect the other APC220 module to the Arduino

10. Reconnect the Arduino to your computer

11. Repeat steps 6 and 7

Installing the CP210x Drivers

To receive data from the APC220 module, you can use another Arduino with the APC220 module connected to it or you can use an UART to USB bridge. This project is designed to work with CP210x.

• Visit the Silicon Labs website

• If you are using Windows, download the driver with the name CP210x Windows Drivers

  

• Extract all the files from the ZIP file in a folder

• Run the CP210xVCPInstaller_x64.exe file and follow the instructions to install the driver

Arduino Setup

There are two versions of the Arduino sketch:

• One with the APC220 module (radio_arduino.ino)
• One without the APC220 module (basic_arduino.ino)

1. Upload one of the two sketches to your Arduino
2. Disconnect the Arduino from your computer

• Connect the GPS module to the Arduino using the following pins:

  GPS Module	->	Arduino
  VCC	->	3.3V
  GND	->	GND
  RX	->	Digital 4
  TX	->	Digital 3

(APC220 Only)

• Connect the APC220 module to the Arduino on the GND, 13, 12, 11, 10, 9 and 8 pins

1. Connect the Arduino to your computer
