Hello Can you please provide actual recommended BOM list for this model ?
Here is a list that I put together. I just built 2 Armchat Compact units using these parts. The only items not included are standoffs and screws to put it together plus two short wires to power the keyboard backlight.

@Kayto, I like what you have done, I'm in the process of doing the same thing. Perhaps it would be better to collaborate. I also plan to upload a few videos on YouTube as well. I recorded my building of the Compact Armchat. I trying to work through the software to see how it works and see if I can fix some bugs that I noticed. I'm also looking for documentation for the configuration of the devices. It seems that I have not been able to locate any documentation on the configuration. I believe I need to uncomment one of the lines to select the correct modem but cannot find information on how to determine which line is the correct line to uncomment. Also see that there is an encryption setting but not certain what a proper setting for this would be.
@richteel sounds good to collaborate. Suggest we now treat this issue as closed.
I will add you as a collaborator on my fork. Might be cleaner like this. I can share the guide for you to add any links etc. I am not much of a programmer but know the settings you refer to.
I have added discussions on my fork to address some questions.
