Re: Arduino Cubesat (satellite) project

By popular request- here is the link to the files on my GitHub.

Some solar panels just arrived so I may pick this project back up. I was hoping to laser cut a new frame but I cant seem to find a decent 1U laser template or SVG files. Still looking though.

This setup allows me to easily connect to inav with the PC in the air and send mission plans etc. I want to try HC12 modules or maybe LORA next :)
