Whoa, I had considered the unleashed board to play around with and bookmarked it, but they are not very overt with the price. I didn't realize it was $1000 USD. You have to click through twice to discover it.
Therefore, they're not a good choice to base a project on.
I do look forward at low power microcontrollers based on risc-v with some actual commitment to continued availability.
