How to Use GPS for lora: Examples, Pinouts, and Specs

The GPS for LoRa module, manufactured by Bigboss, is a high-performance GPS module specifically designed for integration with long-range communication systems utilizing LoRa technology. This module combines precise location tracking with the ability to transmit data over extended distances, making it ideal for applications requiring reliable geolocation and low-power, long-range communication.

• Asset tracking in remote or rural areas
• IoT devices requiring geolocation and long-range communication
• Environmental monitoring systems
• Fleet management and logistics
• Smart agriculture and precision farming

1. Power Supply: Connect the VCC pin to a 3.3V or 5V power source and the GND pin to ground.
2. UART Communication: Connect the TX pin of the GPS module to the RX pin of your microcontroller (e.g., Arduino UNO) and the RX pin of the GPS module to the TX pin of the microcontroller.
3. Antenna: Attach an active external antenna to the module for optimal GPS signal reception.
4. Enable Pin: Ensure the EN pin is pulled high to activate the module.
5. Data Parsing: The module outputs NMEA sentences (e.g., GPGGA, GPRMC) via the UART interface. Use a microcontroller or software to parse this data for location information.

• Antenna Placement: Place the antenna in an open area with minimal obstructions for better GPS signal reception.
• Power Supply: Use a stable power source to avoid fluctuations that may affect GPS performance.
• UART Configuration: Ensure the UART baud rate is set to 9600 (default) on your microcontroller.
• PPS Pin: Use the PPS pin for applications requiring precise timing, such as synchronization in IoT networks.
• LoRa Integration: Pair the GPS module with a LoRa transceiver module to transmit location data over long distances.

Below is an example of how to interface the GPS for LoRa module with an Arduino UNO to read and display GPS data.

#include <SoftwareSerial.h>

// Define RX and TX pins for SoftwareSerial
SoftwareSerial gpsSerial(4, 3); // RX = Pin 4, TX = Pin 3

void setup() {
  Serial.begin(9600); // Initialize Serial Monitor at 9600 baud
  gpsSerial.begin(9600); // Initialize GPS module at 9600 baud

  Serial.println("GPS for LoRa Module Test");
}

void loop() {
  // Check if data is available from the GPS module
  while (gpsSerial.available()) {
    char gpsData = gpsSerial.read(); // Read one character from GPS module
    Serial.print(gpsData); // Print the character to Serial Monitor

    // Note: GPS data is output as NMEA sentences. Use a GPS library like TinyGPS++
    // to parse and extract useful information such as latitude, longitude, etc.
  }
}

1. Can this module be used indoors?

   • While the module may work indoors, GPS signal reception is significantly weaker. Use it in open areas for best results.

2. What type of antenna is recommended?

   • An active external antenna is recommended for optimal performance.

3. Can I change the default baud rate?

   • Yes, the baud rate can be changed using specific configuration commands sent via the UART interface.

4. Is this module compatible with other microcontrollers?

   • Yes, the module is compatible with any microcontroller that supports UART communication, including Arduino, ESP32, and Raspberry Pi.

5. How do I integrate this module with a LoRa transceiver?

   • Use the GPS module to obtain location data and transmit it via the LoRa transceiver using the microcontroller as an intermediary.
