What? This is one of the most ridiculous things I’ve read in awhile and people are up voting this misinformation. No rover that’s on Mars is using a rpi. Here are the actual specs: mars.nasa.gov/mars2020/spacecraft/rover/brains/
I googled around to see where you could have gotten this information from. You might be thinking of this educational rover: github.com/nasa-jpl/…/README.md
