Dave Akerman has worked with Anthony Stirk to create a new GPIO board for the Pi to facilitate high altitude ballooning launches. Called Pi in the Sky, the board comes with the following features:
- Efficient built-in power regulator providing run time of over 20 hours from 4 AA cells
- Highly sensitive UBlox GPS receiver approved for altitudes up to 50km
- Temperature compensated, frequency agile, 434MHz radio transmitter
- Temperature sensor
- Battery voltage monitoring
- Sockets for external i2c devices, analog input, external temperature sensor
- Allows use of Raspbery Pi camera
- Mounting holes and spacers for a solid connection to the Pi
… and comes with a full software suite to complement the outstanding hardware.
Beta testers have successfully flown their sample boards and the production boards are expected to be available mid-late July.
