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.

Perfect product for LoRaWan testing and production. Trackers are working with TTN and also with Helium. Everything perfect. You can easily integrate it with your mapping/tracking, or with a service like Datacake, from both networks.
