The board uses a Hope RFM9x LoRa module and an Arduino Pro Mini (must be the 3.3V 8Mhz version) and a Ublox MAXM8Q GPS.

This is a board only, the RFM9x, Arduino Pro Mini and Ublox MAXM8Q GPS and other components are not supplied.

The completed tracker will transmit its location using the GPS co-ordinates and will be received over hundreds of kilometres when at altitudes above 2km or so. The tracker sends the tracker payload as FSK RTTY as well as LoRa so can be received with standard amateur radio equipment or a PC and SDR combination. The tracker also puts out a very long range location only packet, which is useful for searching for the landed balloon.

When built following the instructions 'HAB2 Minimum Parts Tracker Build.pdf' the tracker when powered by two AAA lithium energizer batteries has an all up weight of circa 20g and is thus suitable for use with low cost foil party balloons filled with helium.

There is sample balloon tracker software in the \examples folder of the at the documentation link. Other tracker software can be found at the SX12xx-LoRa library here; https://github.com/StuartsProjects/SX12XX-LoRa

The original code and instructions for the tracker PCB using a previous LoRa library is to be found here; https://github.com/LoRaTracker/HAB2

Please appreciate that this is the sale of a low cost board only. Example programs and brief build instructions are provided, but it is expected that the constructor has a reasonable amount of experience building and troubleshooting such devices. Detailed asssitance cannot be provided for fault finding or example program modifications. If you not sure read the file 'HAB2 Minimum Parts Tracker Build.pdf' found at the documentation link.
