The M100-5883 GPS module is straightforward to use and can be integrated into a variety of systems. Below are the steps and best practices for using the module:
Wiring the Module:
Installing Required Libraries:
TinyGPS++ library for parsing GPS data.Wire library (built-in) for I2C communication if using the compass.Sample Code: Below is an example Arduino sketch to read GPS data from the M100-5883 module:
#include <TinyGPS++.h> // Include TinyGPS++ library for GPS parsing
#include <SoftwareSerial.h> // Include SoftwareSerial for UART communication
// Define GPS module RX and TX pins
SoftwareSerial gpsSerial(4, 3); // RX = Pin 4, TX = Pin 3
TinyGPSPlus gps; // Create a TinyGPS++ object
void setup() {
Serial.begin(9600); // Initialize Serial Monitor
gpsSerial.begin(9600); // Initialize GPS module communication
Serial.println("M100-5883 GPS Module Test");
}
void loop() {
// Read data from GPS module
while (gpsSerial.available() > 0) {
char c = gpsSerial.read();
if (gps.encode(c)) { // Parse GPS data
if (gps.location.isUpdated()) {
// Print latitude and longitude to Serial Monitor
Serial.print("Latitude: ");
Serial.print(gps.location.lat(), 6);
Serial.print(", Longitude: ");
Serial.println(gps.location.lng(), 6);
}
}
}
}

Q: Can the M100-5883 GPS module be used indoors?
A: While the module can function indoors, GPS signal strength may be significantly reduced. For best results, use the module outdoors with a clear view of the sky.
Q: What is the default baud rate of the GPS module?
A: The default baud rate is 9600 bps.
Q: Can I increase the update rate of the GPS module?
A: Yes, the update rate can be configured up to 10 Hz using specific configuration commands sent via UART.
Q: Does the module support GLONASS or other GNSS systems?
A: No, the M100-5883 GPS module is designed to work with GPS satellites only.
Q: How do I calibrate the compass?
A: Calibration typically involves rotating the module in all three axes while collecting data. Refer to your application or library documentation for specific calibration procedures.
