LightTracker 1.1 (868/915/923MHz)

LightTracker 1.1 (868/915/923MHz) is one of the most affordable, smallest, lightest, powerful and open source LoRa APRS trackers available. It makes tracking pico balloons, weather balloons, model rockets, RC aircraft, and anything else that flies simple and easy. It is able to report location, altitude, temperature and pressure to the internet (LoRaWAN networks such as Helium and TTN) or direct to another LoRa radio module with a solar panel/super capacitors or just 3xAAA batteries. Because LightTracker is open source you can add your own custom sensors via I2C pins.

Important: LightTracker uses unlicensed ISM radio bands which do not require any license to operate. So everyone can use LoRa & LoRaWAN modules.

Information, source code

Official information and source code is on GITHUB: https://github.com/lightaprs/LightTracker-1.1

Key Features

• Ready-assembled PCB: all components are SMD and already soldered
• Open Source: Software is open. You can easily modify the source code. The source code is shared via GitHub for different use cases (pico balloon, HAB, car, etc.)
• Arduino Compatible CPU: You can use Arduino IDE and libraries to programme LightTracker.
• Extendable: Using I2C pins you can add extra sensors (and their libraries) to LightTracker and programme it as you wish.
• High Quality GPS: No need to comment :) Ublox is one of the best GPS manufacturers.
• Low Power Consumption : Power consumption of the module is very low, even transmitting or receiving.
