Only $20? Are there even any voltage modifiers in it, or is it just a pin to pin mapper?

- jws 14y agoThey are active devices.
- josteink 14y agoBecause Apple added DRM to the interface. They are active because Apple made that a requirement. People should stop being apologetic about the bullshit like this which Apple is doing all the time, in small dosages here and there. If you keep taking this, there soon wont be any open, general purpose computing-platforms left.
- jws 14y agoYou are misinformed. There may or may not be DRM according to the teardowns. There is certainly a bit of silicon which has a minimal DRM capability, but it may have come along for the ride. If there is DRM, it is not enforced. There are knockoff connectors out there. The connector electronics are there to allow higher current charging by allocating more pins to power transfer when they are not needed for data and to allow as yet undeveloped higher speed protocols to operate on the same connector. If there is DRM I can see Apple's point. When you destroy an iPhone with a cheap charger that fails, it costs Apple money to replace it. If you attempt to reverse engineer the connector, you will be wrong. The future capabilities are not present for observation. You will probably create a device that behaves improperly for future protocols. Will you destroy that future device by pulling -5V on a low voltage differential data line?
- Dylan16807 14y agoSure, but that chip doesn't have to do anything but authenticate. So what, ten cents?
- cynix 14y agoThat chip has to dynamically map the pins to work with USB. So, probably 20 cents.
