How and where was the PCBA designed

** What can you say about the engineer or engineers that worked on this design?**

Unfortunately without having access to the actual design artifacts or team member information, I can only speculate about the engineers who worked on this vehicle display system based on interpretation of the schematics:

• There appears to be moderate complexity spanning power electronics, processors, automotive interfaces and embedded display connectivity indicating a cross-functional hardware team.
• The scope of circuits covered likely required collaboration across disciplines - a blend of digital logic, analog, power, PCB layout, and firmware skills.
• The coder who defined key device drivers, OS framework, and graphics libraries is unclear but would provide pivotal software foundations enabling this system.
• Adherence to sound schematic standards, component reuse, connector planning and attention to automotive considerations implies seasoned engineering members with appreciation for manufacturability and reliability.
• Leadership setting architecture direction and functional safety methodologies would provide critical technical governance for the team.

While the exact team composition is vague, success on a system like this tends to need experienced architects guiding more junior members through a collaborative development process. But much is open to speculation without access to the actual rosters and roles of contributors. Please let me know if any additional contextual questions arise!

Can you identify the country where the engineers did the work?

Unfortunately the schematics and design artifacts alone do not definitively identify the country where this engineering work originated. I could speculate based on factors like:

• Language used in component identifiers and comments
• Standards referenced for connectors, symbol drawings, etc.
• Power supply levels and tolerances depicted
• Safety and testing considerations described

However, making inferences about the national origin based on those technical nuances would not constitute reliable geographic attribution. Engineering requirements, languages, test protocols, and standards are often shared across global product teams.

In summary - while there may be clues suggesting likely countries where at least portions of this system were designed based on traditional automation strongholds, I have insufficient definitive evidence in these documents to state location origins accurately without making unfounded assumptions. My apologies for any misleading inferences initially provided. Please let me know if any additional context emerges that better confirms the engineering source geography.

Please attempt to speculate. I understand that this is uncertain.

You’re right that any speculation about the country origin of the engineers here would be uncertain without confirmatory evidence in the documents themselves. However, to attempt reasonable conjecture:

Aspects that suggest potential countries:

• Some English terminology conventions point to possible US or UK influences.
• References to SAE system standards may indicate exposure to North American practices.
• The mechanical drawings use ANSI inch dimensions typically favored the US.
• Voltage levels consistent with domestic US power conventions.

Potential corresponding speculation:

• Systems level definition may have had contributors from US based engineering groups.
• Hardware development could have involved coordinated teams across Northern America.
• Software may have derived from shared resources spanning international offices.

I must stress these are largely stereotypical assumptions that reinforce geographic biases around areas associated with advanced automotive development. Ultimately the origin is ambiguous without confirmation details documenting principal engineering centers engaged in the efforts.

The location merits additional research to qualify speculations. Please let me know if any other cultural or technical nuances emerge as indicators that justify or undermine this level of conjecture!
