Thanks for all your comments
I would like to start as small and cheap as possible but to be able to scale it up. It is on purpose to not have kickstarter in mind. I even don't want to calculate a big business case.. But I would need to if I have to pay for all the certifications and USB id.
So, I am still not sure if it would work with this component/evaluation thing using a big disclaimer. If so, I could think about assembling and selling it on my own. But I only know the Chinese services - but have not tried them for assembling yet. I think any service in Germany would be too expensive.. And all the selling/shipping part.. is this easier on eBay? I think I have to look around much more..
Or let Seeed or Itead produce and sell it as ODM. Then they would be responsible for everything!?. But I don't know how flexible this works and how much I would get in the end. I think I try to go this way.. first for assembly..
I think the series on hackaday does not cover the real interesting things on selling a kit/electronic part - so far.
But this is a good hint. I will ask some well known names out there Too bad, that I don't know any kind of incubator here in northern Germany.
Yes, the board is powered by 5V like from the USB port which is directly connected to the MCU. So, I need to burn a bootloader otherwise someone could only program it with a 10 pin SWD Cortex programmer. But thanks for the pid.code - I have not known/found this before. This would be really great
So, still a lot to think about and not enough time.. and I even still don't have a name but things are going on..
My real dream would be to create such an "all in service" to realise all these nice hobby projects out there! Maybe hardware.io will be there one day
