im the guilty one for the cct,PCB and software design. Im only posting here today as Ex-navy wont be back until end August.
normally all questions should go through ex navy.
1) At this stage we are aiming to release the cct board with a standard 9 way Dtype conector so that the user can add thier own cable and switch type.
2) Once full testing is complete connectivity details will be sent with the cct
3) The cct will have a cable attached to the PCB with the correct power socket at the other end to fit the Neuros2 5v.
Im assuming that the same will apply to the "MIC in" and "CAM in" where the user only has to connect to the ( 9way Dtype) hence no soldering to the cct board itself. This was the intention when i designed the PCB
4) Ex-navy is looking into the enclosure
5) The detailed spec has yet to be finlaised, but the cct has a 5v regulator cct for the Neuros 2 only, and a 12v Boost cct for external "stuff" such as MIC and CAM upto a MAX of 2amps. So you could connect a 7v battery to Vin and get 12v out for your cams etc....
6) Aslong as you have a postman im sure it can be sent to you.

Price TBD
Hope this helps a little until Ex-Navy comes back
