TESLA Roadster released open-source per Elon Musk
Information available so far is not full production ready — you can not replicate from parts the TESLA ROADSTER; however, there is information down to legitimate circuit-level detail. Super-interesting regarding the ‘theory’ and also ‘circuits’ which includes altium schematics. — from the comments — “What they released is everything a dealer technician would need to diagnose and repair the car. All manufactures are like this so yes that’s all I would expect.”
