Welcome to Garbee and Garbee, home to Altus Metrum and other fine products! See https://altusmetrum.org for product details, software, and documentation.
TeleGPS is a GPS-based position tracker and logger. It uses the same GPS receiver and radio as our flight computers, but does not include pyro circuits or a flight state machine. It just reports position once a second when moving. This allows the board to be small and light, so that it will fit well anywhere you need a good GPS tracker.
Please note that this board requires a 1S LiPo battery with appropriate JST connector for operation. To ensure proper voltage and polarity, we strongly suggest you buy an Altus Metrum battery for use with TeleGPS!
