This was our first proper flight computer, some electronics development was done before developing this board, but it was mostly focused on testing some specific components. This flight computer was used in our first rocket, Rattlesnake, and it flew successfully twice. It was designed to work as a pathfinder for developing custom electronics for future projects.

Status: Retired 

This was the third version of our flight computer for Astrea-C, our next vehicle after Rattlesnake. In this design we focused on improving the quality of the final electronics using manufactured boards or PCBs, and creating our own circuits to control sensors. We also improved the design of the pyrotechnic channels, including a RBF (Remove Before Flight) switch to arm the pyrotechnic channels just before flight. In this computer we also implemented a ground physical connection that is disconnected during the launch to be able to review and configure the rocket just before flight, and a telemetry system.
