Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.
This is literally just an ad for a product. It even has the price in the title for crying out loud!
And to top it off, it's posted by an account that I'm pretty sure reported me for spam, because I posted a tech-philosophy essay where the site mentioned at the end that the essay was also published in a zine.
Lol, and just immediately downvoted. Lemmy needs that essay more than I thought! Too easy to be reactive without accountability on this platform, sadly
