Thanks for your interest on the project and enthusiasm!
Please keep in mind that the Chordata system is still in beta stage, and many changes are happening on a daily basis. We are only a small team to maintain the hardware-software development and update the documentation. During this period there are good chances that some of the last changes are still not reflected on the docs.
A quick search on the forum is recommended to make sure you get a more or less updated picture of the situation.
For example in this thread answers to your first question:
and the ID_module wiki page also describes it as a deprecated part
HalloweenBob Why is there no replacement part listed for the one that's crossed out on the BOM sheet? The part number that was crossed out is 2214S-06SG-85
It was the connector used to plug the ID_module to the K-Ceptor.
I reviewed your gerber's and they look OK, apart from a warning message.. more about that on the Gerber's thread you opened.
Good look with your building process!
Please keep us updated with the progress here, we'll do our best to help you if you have any doubts! But we do normally take a couple of days to answer.
