The Jetson seems to be a big familiy. The Nano is from 2019 and has some
chip that is most likely based on a chip from 2015? The Orin Nano is
from September 2022 with some CPU that I didn't find on a quick search.
Otherwise, I fully agree with what Joel said: Do we have some audience
for it? They are not really cheap so hobby use is unlikely.
I haven't found any source where I could buy small numbers of blank
chips. In my experience, that often means that the manufacturer targets
products where they sell big numbers of chips (at least 6 digit
numbers). For these it's usually cheaper if the manufacturer just
assigns a field application engineer to you instead of writing good
documentation. If the Jetson falls into that category, it's not an easy

Decent and not too expensive RISC-V would be interesting, but I haven't
found too much of these yet. Only expensive stuff like the Renesas
RZ/Five evaluation board or ones that are not yet easily available like
the Pine Ox64 that I mentioned in other GSoC discussions already. If you
find a nice cheap RISC-V board, it would be a great project. Other
commonly available and well documented non-RISC-V boards or simulator
targets can be interesting projects too.
