If you purchase yourself an iPhone 5 , and are look for acheap , third - political party lightning arranger to save a duo of bucks , you might want to hold off . There ’s an authenticator cow dung in the prescribed adapter , andthird - political party adaptor probably wo n’t operate without it .

Peter fromDouble Helix Cablesfound the obnoxious little chip while analyze one of the new , prescribed Lighting cables . lay between the corduroy ’s USB tangency and the great power pin on the Lightning chew , the chip shot seems to be the Florida key to keeping Lighting cables and adapters proprietary . These kind of hallmark chips are n’t uncommon in more sophisticated accessories , but this is the first time one has show up in something as basic as a charging cable , smell in the middle of the power melodic line . According the Peter , the chip does n’t block the data line , but you need data and power to connect by USB . That could mean any number of thing .
This could intend that it ’s less villainous than a authentication scheme , that it ’s just for superpower regulation – but it look like a serious microcontroller of some variety , it does n’t take care like a garden variety electric potential regulator that I ’ve ever seen . It has a mirror - finish lustrous alloy outside with lasered numeral on it , it does not expect like a generic black IC . If it really costs $ 3.50 for a lightning plug , then it could be something quite high tech . Whatever it is , it ’s expensive and highly miniaturized . And the cable’s length is n’t hold out to work without it , that I can tell at this point .
“ There is fundamentally no way [ third - party adapters ] are useable cables , ” Peter narrate Apple Insider . “ You ca n’t just build a Lightning cable by make something with the same shape and connectivity . ” That signify that all those third - company connectors out there will accommodate the port on your equipment , sure , but they likely are n’t fail to in reality ferment . What appear like a $ 10 , $ 20 , or $ 30 savings could very well wind up being a waste , so if you ’re in a hurry , prescribed adapters are probably the skilful stakes .
If you are n’t , you may sit closely and see if someone can cypher out how to fake those chips , but it could wind up being middling difficult . Peter put it this way in an electronic mail to us :
It remains to be seen whether the chip can be repeal engineered . Nobody that I know of deal to crack the MFi program before , since digital Apple docks and other MFi attest stuff were always quite dear and only coming from well found name sword that participated in the computer programme . I never examine any off brand , super tacky variation of the iPod USB digital audio interfaces that cost hundreds of dollars . If the chip has some code on card that arrive at it authenticate with the iPhone , then it may be hard to duplicate for indisputable . If it ’s doing a “ smart ” procedure like rowlock naming or something unbalanced like that , then it definitely is lead to be mandatory . Apple has say it ’s a “ voguish ” connexion but it is horrifying that just a canonic superpower charging / sync cord like this requires additional complexity . But until some serious engine driver figure out precisely what the chip do ( MFi people are under NDA so I do n’t intend they can tell us without break NDA ) then it remains undefended for debate why this line is like this .
It could take some serious technology brain - baron to get to the bottom of what this chip is really doing . Until then , first - party is the only surefire alternative . [ Apple Insider , Peter ( Double Helix Cables ) ]
