How to Use BN-880 GPS: Examples, Pinouts, and Specs

The BN-880 GPS is a high-performance GPS module designed to provide accurate and reliable positioning data. It features a built-in ceramic antenna, low power consumption, and supports multiple communication protocols, including UART and I2C. The module also includes a 3-axis gyroscope and accelerometer, making it ideal for applications requiring both positioning and orientation data.

Common applications of the BN-880 GPS include:

• Navigation systems for drones, vehicles, and boats
• Robotics requiring precise location and orientation
• IoT devices for geolocation tracking
• Outdoor mapping and surveying tools

The BN-880 GPS module is equipped with advanced features to ensure high accuracy and versatility. Below are its key technical details:

The BN-880 GPS module has a 6-pin interface for easy integration into circuits. Below is the pinout description:

To use the BN-880 GPS module with an Arduino UNO, follow these steps:

1. Wiring: Connect the module to the Arduino as shown below:

   • VCC → 5V on Arduino
   • GND → GND on Arduino
   • TX → Pin 4 on Arduino (for software serial communication)
   • RX → Pin 3 on Arduino (for software serial communication)

2. Install Required Libraries: Install the TinyGPS++ library in the Arduino IDE for parsing GPS data. Go to Sketch > Include Library > Manage Libraries, search for TinyGPS++, and install it.

3. Upload Code: Use the following example code to read and display GPS data on the Serial Monitor.

#include <TinyGPS++.h>
#include <SoftwareSerial.h>

// Create a TinyGPS++ object to parse GPS data
TinyGPSPlus gps;

// Define software serial pins for GPS communication
SoftwareSerial gpsSerial(4, 3); // RX, TX

void setup() {
  Serial.begin(9600);          // Initialize Serial Monitor
  gpsSerial.begin(9600);       // Initialize GPS module communication
  Serial.println("BN-880 GPS Module Test");
}

void loop() {
  // Read data from the GPS module
  while (gpsSerial.available() > 0) {
    char c = gpsSerial.read();
    // Feed the data into the TinyGPS++ library
    if (gps.encode(c)) {
      // If a valid GPS sentence is received, display data
      if (gps.location.isUpdated()) {
        Serial.print("Latitude: ");
        Serial.print(gps.location.lat(), 6); // Print latitude
        Serial.print(", Longitude: ");
        Serial.println(gps.location.lng(), 6); // Print longitude
      }
    }
  }
}

• Ensure the module has a clear view of the sky for optimal GPS signal reception.
• Avoid placing the module near sources of electromagnetic interference (e.g., motors, power supplies).
• Use a stable power supply to prevent voltage fluctuations that may affect performance.
• If using I2C communication, ensure the Arduino supports the required pull-up resistors on the SDA and SCL lines.

1. No GPS Data Received:

   • Ensure the module is powered correctly (3.3V to 5V).
   • Verify the TX and RX connections are not swapped.
   • Check for a clear view of the sky to acquire satellite signals.

2. Incorrect or Inconsistent Data:

   • Wait for the module to achieve a full GPS lock (may take a few minutes).
   • Ensure the baud rate in the code matches the module's default baud rate (9600).

3. Arduino Freezes or Crashes:

   • Ensure the software serial pins (RX/TX) are not used for other purposes.
   • Avoid using the hardware Serial (pins 0 and 1) for GPS communication, as it may conflict with the Serial Monitor.

Q: Can the BN-880 GPS module work indoors?
A: While the module may work indoors, GPS signal strength is significantly reduced. For best results, use the module outdoors with a clear view of the sky.

Q: How do I increase the update rate of the GPS module?
A: The update rate can be configured using u-blox's u-center software. Connect the module to a PC via a USB-to-TTL adapter and use the software to adjust settings.

Q: Can I use the BN-880 GPS with a Raspberry Pi?
A: Yes, the module can be connected to a Raspberry Pi via UART or I2C. Use libraries like gpsd or pyserial to interface with the module.

Q: What is the purpose of the built-in gyroscope and accelerometer?
A: The gyroscope and accelerometer provide orientation and motion data, which can be useful for applications like drones and robotics.
