With a simple wire antenna the board and GPS can weigh as little as 2g. You can also build the board with a small ceramic patch antenna and this weighs 5.9g.
This is a board for the GPS only, you will need to supply your own GPS.
The Quectel GPS perform well and are low cost and low power. You can see a comparision of different types of GPS that StuartsProjects produced here GPS Performance Report.
In its simplest build all you need to do is solder the GPS module to the board, add a 7 pin 0.1” header, a bit of stiff wire for an antenna and make two links.
The Quectel GPSs can be put into 'balloon' mode so that it operates up to 80km altitude. There are examples of this configuration in the tracker applications in this library for LoRa devices;
There are options you can add to the board;
LED fix indicator
GPS backup for hot fixing
Lithium battery or super capacitor
Power switching to turn the GPS off and save power
The board uses 0805 sized surface mount components to keep the size and weight down. Previous experience of SMT assembly is essential and static precautions are needed when assembling and handling the Quectel GPS. All capacitors are ceramic chip types.
The assembled GPS module is for use on 3.3V microcontroller projects only
Do not connect directly to 5V microcontrollers such as the Arduino UNO
