So i decided to try to manufacture a test batch of 10pcs at a factory to see if there are any issues with the layout. I expected some issues with soldering of the small chip U2. And yes there were some boards where this component is not correctly soldered.

What really surprised me was that 2 boards came with destroyed components and pcb, really disappointed and i'm in contact with the factory to get an answer on what happened. Not really hoping to much.

I'm planing to do some crowdfunding on this project and and the campaign is in pre launch stage so i guess there is time to improve production!
