Lighnting connector pin usage

posted on 2015-08-03 00:52:15

For documentary purposes, the used pins on a regular apple USB-to-Lightning cable are like this:

(Shown here are the receptacles, not the plugs themselves!)

LIGHNTNING:

          C  A  A  V
          C  T  T  b           G
          I  A  A  u           N
          D  1  2  s           D

       |  1  2  3  4  5  6  7  8  |

           +--------------+
           |              |
           |  1  2  3  4  |
           +--------------+
              V  D  D  G
              b  A  A  N
              u  T  T  D
              s  A  A
                 1  2

When chargin the phone, these voltages can be measured:

V_bus         = 5.1V
DATA1 / DATA2 = 2.1 to 2.7V
GND           = 0V

ACC_ID        = 0.1V

The measurement difference could be due to my cheap multimeter, I do not know. On the lower side of the lightning connector the values were quite higher for the data channels.

The Accessory ID info is from here.
