RAK5205 LoRa Tracker
The RAK5205 LoRa tracker board is built upon the RAK811. At its core is an STM32L1 microcontroller driving Semtech’s SX1276/78 LoRa chip.
GPS is present as well as a number of sensors. The aforementioned makes the board suitable for rapid application development, such as asset tracking, vehicle management, location-based services, environmental monitoring, etc. Additionally, because of its low power consumption in sleep mode, it can provide a long lasting solution for any battery powered project.
The support for AT commands makes configuration a breeze. For advanced users is open source support in case a custom firmware is required.

Hello, The GPS for this device is giving a location which is 500 meters away from the real location. I tried in open field and lat/long reading is off by 500 meters Is there anyway to adjust this?
For questions of this nature please ask in the forum.
