High altitude balloon project
Here is a quick preview of the board we have been working on for our high altitude balloon project. We will talk about this at an up and coming workshop.
The board has a GPS receiver and a 434MHz telemetry transmitter which are good for 40Km high and 500+km distance. Running from a single AA battery which should be OK for over 20 hours.
It’s a dev. board right now and a bit big. It uses the ATXmega which offers some significant advantages over the standard Arduino in performance, programming, peripherals and power management.
