As far as I can tell, what this project has going for it is just slick marketing. But for me the marketing video is over-produced, form-over-substance, and I can't stand the voiceover or overall tone. It's saccharine.
I see some Cortex-M7 SBCs on AliExpress for $5. Add the rest of it and it's probably like $20 worth of hardware/enclosure and $5 for assembly labor.
They are selling it for $200. So it's like a 700% markup.
