ust a heads up the Habduino telemetry shield is now back in stock. Due to popular requests we are now selling it as a bare board with no radio transmitters so you can select which radios you want.
The board design and code are open source, the kit is supplied with a suitable GPS antenna, and battery clip. The Habduino can do telemetry on 434Mhz and APRS (or at the same time if you buy two transmitters). If you buy the transmitters with the board we will assemble and test for you.
