Ah, oops, sorry! I am guilty of repeating their claim for it, and knowing that the ESP is a cheap chip, not checking
I suppose, perhaps, to give them (and me) the benefit of the doubt, I now realise they are based in a very expensive country, perhaps
the most expensive country in the world!!
Still, it is open hardware so nothing stopping people getting a bunch made locally to reduce costs - or someone in shenzen making a bunch for next to nothing. And as the kickstarter is funded, they will make it and importantly, the software, of which shenzen is not the world master it is in electronics
I think it is a sweet little project, modest but looks good, and at the end we all get some code and hardware designs to see and get ideas from. And maybe it will get cloned and soon we'll see them on aliexpress etc for just a few $.
So we all win!
