I am getting a reading of 1.95V on one of the data pins and 4.65V on the other. The power pin is 5.07V. I do not see bridging on the any of the solder joints. I believe the data pin with the higher voltage is the R3/R4. I tested with brand new energizer AA batteries and the battery in my multimeter is also good. I will be using this with an iphone 4.
Thanks in advance.
I apologize for the picture quality.
The red arrow indicates the data pin with the higher voltage.
