LGT-92 LoRa GPS Tracker User Manual 4 / 29
1. Introduction
1.1 What is LGT-92 LoRa GPS Tracker
LGT-92 is a Long Range / low power consumption LoRaWAN GPS tracker. LGT-92 get user’s
location info via GPS and send it to IoT server via LoRaWAN wireless network.
Compare to traditional GPS tracker, LGT-92 use much lower power consumption hence can last
for longer time. It doesn’t need cellular service; system integrator can build their own tracking
network base on LoRa technology.
LGT-92 uses STM32l0x chip from ST, STML0x is the ultra-low-power STM32L072xx
microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0
crystal-less) with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32
MHz frequency, a memory protection unit (MPU), high-speed embedded memories (192 Kbytes
of Flash program memory, 6 Kbytes of data EEPROM and 20 Kbytes of RAM).
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.
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.
