The rocketry team at my university is thinking of using a PixHawk as the flight computer for our rocket. We are building this rocket ourselves witha hybrid engine. The expected burntime is 5 seconds and maximum altitude around 1050 meters. We expect a maximum acceleration of 5G. We will not be using the PixHawk for anything except a flight computer and telemetry (no wings, or trajectory adjustment of any sort).
Which PixHawk should we use? Even limiting to two options will help since there are several different PixHawks and its hard to know which is best.
What we found attractive is the fact that Pixhawk already incorporates some of the sensors we need, as well as even having an easy way to connect telemetry.
However, we do have other sensors such as temperature and pressure sensors we’d like to attach, will these be able to also be used on a PixHawk?
Lastly, how difiicult will it be to format code to fit the PixHawk system? We are debating whether it may be easier to use a more free source MCU/MPU such as arduino, raspberry Pi, or stm.
