LGT92 LoRaWAN GPS Tracker includes a low-power GPS module L76-L and a 9-axis accelerometer for motion and attitude detection. MCU can control the power for both the GPS module and accelerometer to achieve the best energy profile for different applications.
The LoRa wireless technology used in LGT92 LoRaWAN GPS Tracker allows users 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 minimizing current consumption. It targets professional tracking services.


LGT92 LoRaWAN GPS Tracker series products include two major variants:
- LGT-92-LI: is powered by a 1000mA rechargeable Li-on battery and charging circuit, which targets real-time tracking with a 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 you only need to uplink a few times every day.
LGT92 LoRaWAN GPS Tracker is an open-source product, it is based on the STM32Cube HAL drivers, and lots of libraries can be found on the ST site for rapid development.
