There are plenty of uses for a reliable GPS tracker, but in order to fully realize them you need two things: a wide range and a long battery life. The LGT-92 Dragino LoRaWAN GPS Tracker seeks to fill both of these roles by offering a combination of an Ultra Low Power STM32L072 MCU and a SX1276/1278 LoRa module into one device.
The inclusion of a 9-axis accelerometer that’s controllable by an MCU allows you to also tweak the energy profile for a variety of different purposes. Thanks to the LoRa wireless tech, users are able to send data across massive distances using low data-rates.
The ultra-long range spectrum allows for easy communication and protection from interference while also keeping power consumption low. The device is powered by a 1000mAh Li-on battery which, combined with the proper programming, will allow the device to last for weeks or even months depending on the use case.
The LGT-92 is open source, based on STM32Cube HAL drivers, with plenty of libraries available for quick and easy development.
