Dragino LGT-92 LoRaWAN GPS Tracker
The Dragino LoRaWAN GPS Tracker LGT-92 is an open source GPS tracker based on the Ultra Low Power STM32L072 MCU and SX1276/1278 LoRa module.
The LGT-92 includes a GPS module and the MPU9250, a low-power 9-axis accelerometer for motion and orientation detection. Power for both the GPS module and the accelerometer can be controlled by the MCU to achieve the best power profile for different applications. The LGT-92-LI is powered from a rechargeable 1000 mAh Li-on battery. You can program the tracker to work for weeks to months, depending on its intended use.
The LGT-92 comes preloaded with firmware and is configured as LoRaWAN OTAA Class A mode by default. To connect to a local LoRaWAN network, all you need to do is enter the OTAA keys into the LoRaWAN IoT server and turn on the LGT-92.
The LGT-92 is an open source product based on the STM32Cube. HAL drivers and many libraries can therefore be found on the ST site. An application can therefore be developed fairly quickly.
Included are a USB charging cable and a USB cable with loose connecting wires at the other end. This cable is used in conjunction with a USB to TTL adapter to connect to a PC to optionally configure the device using AT commands.
