Description

Tiny LoRa-based GPS tracker for balloon experiments

README

TinyTracker

The plan is to create a tiny (<5g) tracker for low-cost, lightweight balloon experiments.

Currently no electronics have been built, but an initial design has been made using KiCad. This is untested and likely has some mistakes. It features:

• M10748 GPS
• SX1276 based LoRa radio with TCXO (for ultimate performace with very low data rates)
• STM32F048 MCU
• MS5637 temperature/pressure sensor
• CAT24M01 EEPROM for logging

It is designed to run off a small lithium polymer battery such as PRT-00731 which, depending on logging and transmission interval, should give a battery life of over 10 hours.
