7Semi L89 Breakout Multi-GNSS engines for GPS, IRNSS, GLONASS, BeiDou, Galileo and QZSS

The Evelta L89 Breakout Multi-GNSS IRNSS-enabled integrates Quectel’s IRNSS-enabled GNSS module measuring 26.4mm × 18.4mm × 6.8mm, with two embedded antennas so it can work on L1 and L5 bands simultaneously. The board operates on 3.3V power supply and communicates with the target MCU through I2C / UART interface TX, RX, and a BAT connection pin for a backup power supply is also available. The L89 breakout can acquire and track GPS, IRNSS, GLONASS, BeiDou, Galileo and QZSS signals, reducing time-to-first-fix and allowing accurate navigation.

Arduino Code for GPS Read

#include <SoftwareSerial.h> // Include the SoftwareSerial library
#define ARDUINO_GPS_RX 9 // Arduino RX pin connected to GPS TX
#define ARDUINO_GPS_TX 8 // Arduino TX pin connected to GPS RX
#define GPS_BAUD_RATE 9600 // The GPS Shield module defaults to 9600 baud
// Create a SoftwareSerial object called gps:
SoftwareSerial gpsPort(ARDUINO_GPS_TX, ARDUINO_GPS_RX);

// This is the hardware serial port on pins 0/1.
#define SerialMonitor Serial

void setup()

}

void loop()

if (SerialMonitor.available()) // If SerialMonitor data is available
gpsPort.write(SerialMonitor.read()); // Read it and send to GPS
