Im looking into my Phantom 3 4K and the main ESC board looks like the ESC board from a Phantom 3 Standard...
Can anyone tell me if this is correct?  (does the P3 4k use a P3 Sta ESC board?)

Thanks
Greg

Answered my own question...the hard way.
I had a crash recently that cracked my GPS module... and I now see the P3 4K ESC board is slightly different than the P3 Standard ESC board.
Next to the rectangular shield cover there are two connectors, one for the Compass(that's on the Standard ESC) and one for the Visual Positioning/OFDM module(Not on the Standard ESC).

Note: The flat ribbon cable that runs from the 4K ESC to the OFDM unit looks the same as the P3 Pro/Adv cable, ... but the pins are actually reversed.Observed by holding the P3 Pro/Adv cable next to the P3 4K cable.
You can not use a P3 Pro/Adv OFDM flat ribbon cable as a replacement in the 4K.
