🔌 Components & Wiring Guide

Components & Wiring Guide

The components needed for this project are:
  • ATGM336H GPS+BDS Module with Antenna: receives GPS and BDS signals to determine location
  • Arduino UNO: microcontroller to process and display location data
  • Jumpers: connect components to the breadboard and Arduino
  • Breadboard: platform for connecting and organizing components
To connect the components, follow these steps: The ATGM336H GPS+BDS Module has the following pins: VCC, GND, TX, and RX. Connect the VCC pin of the ATGM336H module to the 5V pin on the Arduino UNO using a jumper. Next, connect the GND pin of the ATGM336H module to the GND pin on the Arduino UNO using a jumper. Then, connect the TX pin of the ATGM336H module to the RX pin (pin 0) on the Arduino UNO using a jumper. Finally, connect the RX pin of the ATGM336H module to the TX pin (pin 1) on the Arduino UNO using a jumper. The ATGM336H module should be placed on the breadboard, with the jumpers connecting it to the Arduino UNO.

Additional Considerations

When working with the ATGM336H GPS+BDS Module, ensure the antenna is positioned for optimal signal reception, ideally with a clear view of the sky. Be aware that the ATGM336H module operates at a voltage of 5V, which is compatible with the Arduino UNO. No high voltage or high current is involved in this project, but it is still essential to handle the components with care to avoid damage.

🛠️ Step-by-Step Guide

Introduction to the ATGM336H GPS+BDS Module

The ATGM336H GPS+BDS Module is a compact and powerful navigation module that provides location information using both GPS and BeiDou Satellite Systems. This module is ideal for various applications, including tracking systems, navigation devices, and IoT projects. In this tutorial, we will explore how to use the ATGM336H GPS+BDS Module with an Arduino Uno to track location and display it in the serial monitor.

Setting Up the Hardware Components

To start, you will need the following hardware components: ATGM336H GPS+BDS Module with Antenna, Arduino UNO, Jumpers, and a Breadboard. You can source these components from SoftTech Supply in Kigali, Rwanda. Make sure to handle the components with care, as they are sensitive electronic devices.

A safety note: when working with electronic components, make sure to avoid touching the pins or electrical paths to prevent damage or short circuits.

Wiring the ATGM336H GPS+BDS Module to the Arduino UNO

Now, let's connect the ATGM336H GPS+BDS Module to the Arduino UNO. The wiring is straightforward:

  • Connect the VCC pin of the ATGM336H GPS+BDS Module to the 5V pin of the Arduino UNO
  • Connect the GND pin of the ATGM336H GPS+BDS Module to the GND pin of the Arduino UNO
  • Connect the TX pin of the ATGM336H GPS+BDS Module to Arduino UNO Digital Pin 2 (GPS receive pin defined as gpsRx)
  • Connect the RX pin of the ATGM336H GPS+BDS Module to Arduino UNO Digital Pin 3 (GPS transmit pin defined as gpsTx)

Use the jumpers to connect the module to the Arduino UNO, and the breadboard to organize the connections.

Firmware Upload and Configuration

Next, you need to upload the firmware to the Arduino UNO. You can use the Arduino IDE to upload the code. Create a new project, and include the following libraries: SoftwareSerial.h. Then, create a SoftwareSerial object to communicate with the ATGM336H GPS+BDS Module.

Use the following code snippet to configure the serial communication: SoftwareSerial mySerial(2, 3). Replace the pins with the actual pins you used to connect the module.

Writing the Code to Read GPS Data

Now, let's write the code to read the GPS data from the ATGM336H GPS+BDS Module. You can use the following code as an example:

The code will read the GPS data, parse the NMEA sentences, and extract the location information. You can then print the location information to the serial monitor.

Testing the Project

Once you have uploaded the code, open the serial monitor to see the location information. The serial monitor will display the latitude and longitude coordinates, as well as a link to open Google Maps with the location. The link will be in the format: https://maps.google.com/?q=-1.94536,30.05970

Make sure to place the GPS module near a window or outside to get a clear view of the sky, as this will improve the GPS signal reception.

Troubleshooting Tips

If you encounter any issues during the project, here are some troubleshooting tips:

  1. Check the wiring connections to ensure they are secure and not loose
  2. Verify that the GPS module is configured correctly and has a clear view of the sky
  3. Check the serial monitor for any error messages or debugging information
  4. Make sure to use the correct baud rate and serial configuration in the code

By following these tips, you should be able to resolve any issues and get the project working as expected.

💻 Sample Code 

// ATGM336H GPS+BDS Module with Arduino Uno

#include <SoftwareSerial.h>

const int gpsRx = 2;  // Arduino RX (connect to GPS TX)
const int gpsTx = 3;  // Arduino TX (connect to GPS RX)

SoftwareSerial gps(gpsRx, gpsTx);

void setup() {
  Serial.begin(9600);
  gps.begin(9600);

  Serial.println("GPS Starting...");
}

void loop() {

  if (gps.available()) {

    String gpsData = gps.readStringUntil('\n');

    // Look for GGA sentence
    if (gpsData.startsWith("$GPGGA")) {

      Serial.println(gpsData);

      int comma[14];
      int index = 0;

      comma[index++] = -1;

      for (int i = 0; i < gpsData.length(); i++) {
        if (gpsData.charAt(i) == ',') {
          comma[index++] = i;
        }
      }

      // Extract latitude and longitude
      String latitude = gpsData.substring(comma[1] + 1, comma[2]);
      String latDirection = gpsData.substring(comma[2] + 1, comma[3]);

      String longitude = gpsData.substring(comma[3] + 1, comma[4]);
      String lonDirection = gpsData.substring(comma[4] + 1, comma[5]);

      Serial.print("Latitude: ");
      Serial.print(latitude);
      Serial.println(latDirection);

      Serial.print("Longitude: ");
      Serial.print(longitude);
      Serial.println(lonDirection);
