  • LoRaWAN GPS Tracker Ultra Low Power with 9-axis Accelerometer - LGT92 (AU915 & AS923 MHz)

    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 L70 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 is powered by 1000mA Li-on battery, user can program the device to work from weeks to months depends on the target use case.

    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.
