Re: A look at an original iPhone prototype
#2Seeing what looks like a full iPhone attached to it (I know it's just the screen, but the inclusion of a taped-over home button is interesting) gives me kind of a "Thinking quickly, Dave constructed an iPhone using a circuit board, some tape, and an iPhone" vibe.

#3That's really interesting. Whose job is it to actually design and develop the prototype board? It seems like that team would have to know quite a bit, if not nearly everything, about the device.

Usually the design engineer that handles the production board goes through the EVT boards.
Basically the purpose of EVT to a) ensure all the components identified in the initial survey/design review actually work together b) enable software development early in the process c) iron out any showstoppers and kinks that could jeopardize the project later on.
The next few design stages usually get rid of all the super-debug stuff (such as the ethernet port on the iphone; also maybe get the form factor down) while still retaining the regular debug stuff (JTAG etc). This usually when mechanical can jump in and preliminary compliance stuff can take place (EMC etc)

That's how most prototype boards are. The idea being you can do develop / do bring up and see the graphics / boot etc.

I was also curious about that. In other stories I've read, I've heard it referred to as a big ugly box with a touch screen embedded on top of it, which is what I imagined most people worked on. But this just looks like a normal iPhone with a large breadboard connected.

#7Does it connect to my airpods though? :)

The new AirPods supposedly require "an iCloud account and macOS 10.14.4, iOS 12.2, or watchOS 5.2", so it doesn't look like it :P

#9Very dull content for anyone who has worked on anything related to mobile phone HW during the past 20 years. Every manufacturer has similar prototype boards and there is nothing special in this iPhone prototype.

#10Is it me or does it look like the top layer has reaaaaally thick copper? Look at how it differs between areas with those squares contra area without. Looks like it's very very thick. Perhaps the solder mask.
