Satellite Systems: GPS, GLONASS, BEIDOU
Accuracy: 2.5m CEP (50%)
Update Rate: Up to 10 Hz
Compass: 3-axis magnetometer
Operating Voltage: 3.3V to 5V
Communication Interface: UART, I2CCode Examples### Example 1: Using the NEO M8N GPS Module with APM Autopilot (C++)This example demonstrates how to use the NEO M8N GPS Module with the APM autopilot system to read GPS data and compass orientation.
```cpp
#include <AP_GPS.h>
#include <AP_Compass.h>AP_GPS gps;
AP_Compass compass;void setup() {
Serial.begin(115200);
gps.init();
compass.init();
}void loop() {
gps_data_t gps_data;
compass_data_t compass_data;if (gps.read(gps_data)) {
Serial.print("GPS: ");
Serial.print("Lat: ");
Serial.print(gps_data.latitude degrees);
Serial.print(", Lon: ");
Serial.print(gps_data.longitude degrees);
Serial.print(", Alt: ");
Serial.println(gps_data.altitude meters);
}if (compass.read(compass_data)) {
Serial.print("Compass: ");
Serial.print("Roll: ");
Serial.print(compass_data.roll degrees);
Serial.print(", Pitch: ");
Serial.print(compass_data.pitch degrees);
Serial.print(", Yaw: ");
Serial.println(compass_data.yaw degrees);
}delay(50);
}
```
### Example 2: Using the NEO M8N GPS Module with Arduino (Arduino Sketch)This example demonstrates how to use the NEO M8N GPS Module with an Arduino board to read GPS data.
```cpp
#include <SoftwareSerial.h>
#include <TinyGPS++.h>#define GPS_TX 5
#define GPS_RX 6SoftwareSerial gpsSerial(GPS_RX, GPS_TX);
TinyGPSPlus gps;void setup() {
Serial.begin(115200);
gpsSerial.begin(9600);
}void loop() {
while (gpsSerial.available() > 0) {
if (gps.encode(gpsSerial.read())) {
if (gps.location.isValid()) {
Serial.print("GPS: ");
Serial.print("Lat: ");
Serial.print(gps.location.lat(), 6);
Serial.print(", Lon: ");
Serial.print(gps.location.lng(), 6);
Serial.print(", Alt: ");
Serial.println(gps.altitude.meters());
}
}
}
delay(50);
}
```
### Example 3: Using the NEO M8N GPS Module with Python (Raspberry Pi)This example demonstrates how to use the NEO M8N GPS Module with a Raspberry Pi running Python to read GPS data.
```python
import serial
import pynmea2gps_serial = serial.Serial('/dev/ttyUSB0', 9600, timeout=1)while True:
data = gps_serial.readline()
if data:
msg = pynmea2.parse(data.decode('utf-8'))
if isinstance(msg, pynmea2.GGA):
print("GPS: ")
print("Lat: ", msg.latitude)
print("Lon: ", msg.longitude)
print("Alt: ", msg.altitude)
elif isinstance(msg, pynmea2.RMC):
print("Compass: ")
print("Roll: ", msg.roll)
print("Pitch: ", msg.pitch)
print("Yaw: ", msg.yaw)
gps_serial.flush()
```
