7Semi L89HA Breakout Multi-GNSS engines for GPS, IRNSS, GLONASS, BeiDou, Galileo and QZSS

The 7Semi's L89HA Breakout Multi-GNSS IRNSS-enabled integrates Quectel’s IRNSS-enabled GNSS module 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.

The L89HA Breakout is a high-performance multi-GNSS (Global Navigation Satellite System) engine that supports GPS, IRNSS, GLONASS, BeiDou, Galileo, and QZSS satellite systems.

This compact and versatile GNSS module is designed to deliver highly accurate and reliable positioning data, making it ideal for a wide range of applications including navigation, tracking, timing, and geofencing.

One of the key features of the L89HA Breakout is its 3.3V power supply, which makes it easy to integrate into a wide range of systems and devices.

It also features both I2C and UART interfaces, providing flexibility and compatibility with a wide range of microcontrollers and processors.

Another advantage of the L89HA Breakout is its embedded patch antenna and chip antenna, which helps to simplify the design and reduce the size of the overall system.

This makes it ideal for use in compact and mobile devices such as smartphones, wearables, drones, and IoT devices.

The L89HA Breakout also boasts high sensitivity and accuracy, thanks to its advanced RF design and signal processing algorithms.

It supports concurrent reception of up to three GNSS constellations, enabling it to deliver highly accurate and reliable positioning data even in challenging environments such as urban canyons and under tree canopies.

The L89HA Breakout is a versatile and powerful multi-GNSS engine that offers high accuracy, reliability, and flexibility.

With its 3.3V power supply, I2C / UART interface, and embedded patch antenna and chip antenna, it is an ideal choice for a wide range of navigation, tracking, and timing applications.

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()
{
gpsPort.begin(GPS_BAUD_RATE);
SerialMonitor.begin(9600);
}

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