More Detail

Overview

The Dragino LoRaWAN GPS Tracker LGT-92 is an open source GPS tracker base on Ultra Low Power STM32L072 MCU and SX1276/1278 LoRa Module.

LGT-92 includes a low power GPS module L76-L and 9-axis accelerometer for motion and attitude detection. The power for both of the GPS module and accelerometer can be controlled by MCU to achieve the best energy profile for different applications.

The LoRa wireless technology used in LGT-92 allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional tracking service.

Features

  • LoRaWAN 1.0.3 compliant

  • Regular/ Real-time GPS tracking

  • Built-in 9 axis accelerometer

  • Motion sensing capability

  • Power Monitoring

  • Charging clip with USB port  (for LGT-92-LI)

  • 1000mAh Li-on Battery power (for LGT-92-LI)

  • 2 x AA battery holder (for model LGT-92-AA)

  • Tri-color LED, Alarm button

  • Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915

  • AT Commands to change parameters

The Dragino LoRaWAN GPS Tracker LGT-92 is an open source GPS tracker base on Ultra Low Power STM32L072 MCU and SX1276/1278 LoRa Module.

LGT-92 includes a low power GPS module L76-L and 9-axis accelerometer for motion and attitude detection. The power for both of the GPS module and accelerometer can be controlled by MCU to achieve the best energy profile for different applications.

The LoRa wireless technology used in LGT-92 allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional tracking service.

LGT-92 series products include two major variants:

  • LGT-92-LI: is powered by 1000mA rechargeable Li-on battery and charge circuit, which target for real time tracking with short tracking uplink.
  • LGT-92-AA: Disable the charge circuit to get the lowest power consumption and power directly by AA batteries. This is designed for asset tracking where only need to uplink a few times every day.

LGT-92 is an open source product, it is based on the STM32Cube HAL drivers and lots of libraries can be found in ST site for rapid development.
