Yes it's here.
The PCB and all components are here and we have mounted them.
All the tests have been passed, and now we can use the power supply adapter for our projects.
We have also tested the version with the printer USB connector.
To reach the low cost goal we have bought the components for about 30 pieces, if you are interested in one of them you can go here or you can post a message to this post.
