LGT-92 LoRaWAN GPS Tracker with 9-Axis Accelerometer

$39.50

The Dragino LoRaWAN GPS Tracker LGT-92 is an open source GPS tracker based on an ST Micro Ultra Low Power STM32L072 MCU and Semtech SX1276/1278 LoRa Module. It is available in two primary variants for different applications. In addition, the LGT-92 is an open source product with hardware and software source code available. It is based on the STM32Cube HAL drivers and many libraries can be found on the ST Micro site for rapid development.

Product Description

The LGT-92 includes a low power GPS module (L76-L) 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 LoRaWAN wireless technology used in LGT-92 allows the user to uplink data, and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity while minimizing power consumption. The product is designed to target both consumer and professional GPS tracking services.

The LGT-92 series products include two major variants:

  • LGT-92-LI: this version is powered by a 1000mAh rechargeable Li-on battery and charge circuit. It is designed for near-real-time tracking with short tracking uplink intervals.
  • LGT-92-AA: this version has the charge circuit disabled to get the lowest power consumption and power directly by AA batteries. This is designed for asset tracking applications where you only need to uplink a few times every day.
