This is an old revision of the document!
for some reason i just backed a kickstarter (first one, i think), its an AI on a chip thing, called HuskyLens.
not bad for 25$
digging a bit, after the quick click i actually read the description and found its core is a Kendryte K210 IC.
and of course there is already an aliexpress dev board going.
