On January 9, 2007, Jobs released the first generation of the iPhone. In 12 years, people first saw the EVT (Engineering Verification Machine) of the first generation of the iPhone.
This EVT validator is so primitive that components are distributed on a large motherboard, typically serving developers, to test various functional modules. According to the development board collector theredm68, for the sake of confidentiality, most engineers'development boards can not see the screen at all and need external display. Fortunately, this display has LCD components and can be lit up.
In addition, there are serial interface (test iPod), 3.5mm input and output, 4 GB Samsung flash memory, 30-pin interface, power/volume key, camera, Home key, single-core ARM11 processor stacked Samsung K4X1G153PC memory (ARM1176JZF), network port, communication baseband module (Intel, Infineon, Mingman, Skyworks, CSR chip), SIM card slot, test call RJ11. Interface and so on.
Collector's introduction, prototype code M68, project name Purple 2.
Maybe you noticed that the motherboard was printed in red, which is said to be Apple's only preference for prototypes, with production opportunities in green or blue.
